What is an industrial furnace pit?
In twentieth Century 50s, coreless induction furnaces were developed rapidly. Later, electron beam kilns, using electron beams to impact solid fuels, strengthen the surface to heat and fuse materials with high melting point.
The creation and development of industrial kilns play an important role in the progress of mankind. Chinese appeared more perfect in the Shang Dynasty copper smelting furnace, furnace temperature is up to 1200 DEG C, up to 0.8 meters in diameter kiln stove.
Later, a chamber kiln with a semi closed or fully enclosed kiln made of refractory bricks can be used as fuel for coal, gas or oil, and electricity can be used as heat source. The workpiece will be heated in the kiln hearth.
