We all know that there are many advantages of high temperature vacuum furnace atmosphere, either in life or work or experiments are of great help for us, but a lot of people when using high temperature vacuum furnace atmosphere experiment for the use of high temperature vacuum atmosphere furnace considerations often don't pay attention to, small make up to you today about high temperature vacuum furnace atmosphere in the experiment we need to pay attention to those issues.
The structure, temperature control, heating technology and atmosphere of high temperature vacuum atmosphere furnace will directly affect the product quality after the production of vacuum furnace. In forging furnace, increasing metal temperature can reduce melting resistance, but too high temperature will cause grain oxidation or overburning, which will seriously affect the product quality in vacuum furnace. During heat treatment, if the steel is heated to a point above the critical temperature and then suddenly cooled by cooling hair, the hardness and strength of the steel can be improved. If heated to a point below the critical temperature and cooled slowly, the steel can be made more ductile.
In order to obtain a smooth surface and size of the workpiece, or in order to reduce metal oxidation to achieve the purpose of protecting the mold, reduce machining allowance, etc., can use a variety of less oxidation free heating furnace. In the open flame less oxidization-free heating furnace, reducing gas is generated by the incomplete combustion of fuel, in which the workpiece is heated, the oxidation loss rate can be reduced to less than 0.6%.
