By way of example, please refer to the following table,
table 1: reduction tank for 3 tons of titanium sponge
Table 2: reduction tank for 5 ton titanium sponge
Table 3: reduction tank for 7-10 tons of sponge titanium
The table shows different combinations of carbon steel plates and stainless steel plates with different thicknesses and materials under different production specifications, and the service life of the carbon steel plates and the stainless steel plates is measured and calculated through experiments.
