Stainless Steel Silica Sol Casting Process

The furnace opening process for stainless steel silica sol casting involves several critical steps to ensure the quality and accuracy of the castings.

The following are the main steps and considerations for opening the furnace:

1、 Wax mould making: firstly, three-dimensional modelling design according to product drawings, then mould design and manufacturing. The code of practice for wax treatment process includes the steps of static dewatering, stirring evaporation dewatering and static decontamination of the wax to ensure the purity and quality of the wax.

2、Shelling, dewaxing, melting and pouring: After the wax moulds are made, the processes of shelling, dewaxing and melting and pouring are carried out. These steps require strict temperature and time control to ensure the quality and dimensional accuracy of the castings.

3、Cleaning, heat treatment and finishing: After the castings are finished, cleaning, heat treatment and finishing processes are needed to remove impurities on the surface of the castings and improve the mechanical properties of the castings.

4、the implementation of process control: the entire production process should be carried out in strict accordance with the requirements of the code of technology and process regulations, the implementation of process control, and make a good original records of the process.

5、Note: In the process of opening the furnace, you need to pay attention to the equipment, temperature control instrumentation to prevent loss of control. At the same time, the residual water and dirty debris in each drum should be drained regularly to keep the wax pure.
