Push rod furnace principle Push rod furnace, also known as push rod heating furnace, is a common industrial heating equipment. Its principle is to transfer high-temperature gas in the combustion chamber to the object to be heated through a push rod to achieve heating. This article will introduce in detail the working principle of the push rod furnace and its applications.Debinding and sintering of metal injection molding components 1. Working principle of push rod furnace The working principle of the push rod furnace is to use the push rod to transfer the high-temperature gas in the combustion chamber to the object to be heated, so that it reaches the required temperature. The push rod furnace is mainly composed of a combustion chamber, a push rod and a heating area.Research on vacuum brazing technology of dissimilar metals The combustion chamber is the core component of the push rod furnace, which generates high-temperature gas by burning fuel. The fuel in the combustion chamber can be natural gas, liquefied gas or solid fuel. When fuel burns in the combustion chamber, a large amount of heat energy is generated, which increases the temperature in the combustion chamber.Effect of filler metal on vacuum brazing of cemented carbide and steel The push rod is an important component that connects the combustion chamber to the heating zone. It is located at one end of the combustion chamber and transfers the high-temperature gas in the combustion chamber to the heating zone by pushing it. The material of the push rod needs to be resistant to high temperatures and corrosion, and is usually made of high-temperature resistant alloys or ceramic materials.Vacuum sintered powder alloy high speed steel Posted at 01:06 AM

Types of tube heating furnaces According to the appearance, they are roughly divided into the following four categories: box furnaces, vertical furnaces, cylindrical furnaces, and large square furnaces. This classification method is based on the appearance of the radiation chamber and has nothing to do with the convection chamber. The so-called box furnace, as its name implies, has a radiation chamber that is a "box-shaped" hexahedron. Vacuum brazing in automotive heat exchangers Compared with it, the width of the radiation chamber of the vertical furnace is narrower, and the ratio between the distance between the two side walls and the height of the furnace is about 1:2. The names of cylindrical furnace and large square furnace are also derived from the same reason. This is an early type of tube furnace.Vacuum brazing in automotive heat exchangers The burner burns horizontally, and the flue gas flows from top to bottom through the convection chamber across the partition wall between the radiant chamber and the convection chamber. The main disadvantage of this furnace type is the tube laying rate (the radiant chamber row has The ratio of the furnace wall of the tank to the total furnace wall area of the radiation chamber is low, and the furnace is large; the furnace tube needs to be hung with alloy, which is expensive; and an independent chimney is required. It is almost no longer used these days.Heat treatment process for wide and thick plates The furnace space and furnace walls are utilized. Their advantage is that as long as the number of central partition walls is increased, the furnace can be enlarged in a "building block combination" while keeping the heating intensity of the furnace volume unchanged, so they are particularly suitable for large furnaces. When the heat load is large, although They also suffer from some of the inherent disadvantages of box furnaces, which are offset by the advantages mentioned above.Process Of Preventing Deformation And Cracking Of Mold By Vacuum Heat Treatment Posted at 01:05 AM

Basic knowledge of tube heating furnace What is combustion? What are the basic conditions for combustion? Answer: Combustion is a process in which substances combine with each other and produce light and heat. What we usually call combustion refers to the violent chemical reaction between combustibles and oxygen in the air. A certain temperature is required when a combustible material burns. The minimum temperature required when a combustible material begins to burn is called the ignition point or ignition point of the material.Application of sintering technology in semiconductors The basic conditions for material combustion: first, combustibles, such as fuel oil, gas, etc.; second, there must be combustion accelerants, such as air, oxygen; third, there must be an open flame or a high enough temperature. Combustion cannot occur without one of the three. This is the "three conditions of combustion" or the "three elements of combustion".Effect of vacuum heat treatment on the properties of powder metallurgy products What are radiation heat transfer and convective heat transfer? Answer: Radiation heat transfer is a process of transferring energy by electromagnetic waves. The energy transferred is called radiant energy. Radiation has dual properties of particulate (photons) and wave (electromagnetic waves). Heat treatment process for wide and thick plates Convective heat transfer is the transfer of heat from one part of space to other parts by moving liquid or gas particles relative to each other.Optimizing vacuum heat treatment of spring steel Posted at 01:16 AM

Aging furnace strengthening mechanism The method of increasing the strength and hardness of aluminum alloys by naturally parking them at room temperature for a certain period of time is called natural aging. The method of keeping aluminum alloy products at a certain temperature higher than room temperature for a certain period of time to improve the strength and hardness of the aluminum alloy is called processing aging.Vacuum Hardening and Vacuum Tempering Heat Treatment for Metal Parts For the Al-Mg-Si 6063 alloy, natural aging proceeds very slowly. Staying for half a month, or even longer, will not achieve the best strengthening effect. The strengthening effect is 30% to 50% worse than the strengthening effect of the aging process, so the aging process is generally used. Alloys containing the main strengthening phases Mg; Si, MgZn and Al-Mg, Zn can only obtain the highest strength by aging.Enhanced Steel Performance During Vacuum Carburizing of Gears Alloys containing the main strengthening phases CuAl and S(A1:CuMg) are naturally aged and processed.Both aging methods are available. For example, 2A11 and 2A12 alloys can achieve the best strengthening effect by using natural aging or in-process aging. Practical Technology For Low Pressure Vacuum Carburizing Heat Treatment Which aging method is used depends on the nature and use of the alloy. Generally, deformed aluminum alloys that work at high temperatures usually use working aging, while deformed aluminum alloys that work at room temperature should use natural aging.Production Process Of Vacuum Brazed Diamond Saw Blade Posted at 02:18 AM |
