Carbon calcining furnace is an important thermal equipment in the production of carbon materials. Its main function is to heat the calcined carbon products to a certain temperature to enhance the thermal conductivity, electrical conductivity and material strength of the materials. The carbon baking furnace is made of refractory materials. In the masonry process, the general regulations for its construction are as follows:
1. The thickness of the masonry brick joints in various parts of the carbon calciner and the carbon roaster should meet the values specified in Table 1.
Before the construction of the carbon calciner and the carbon roaster, the furnace foundation should be retested. The steel components in the lower part of the carbon calcination tank are installed and should be inspected before they can be constructed.
The air passages, exhaust passages, volatile passages and fire passages of various parts of the carbon calciner and the carbon roaster should be thoroughly cleaned before reversing and closing, and the channels should be clean and unblocked.
The calcination tank and combustion fire channel of the carbon forging furnace, the material wall of the closed roaster, the bunker brick and the furnace cover, and the fire and cross walls of the open roaster should be pre-built.
2. The allowable deviation of the masonry carbon calciner should meet the values specified in Table 2.
The elevation of the masonry in each part of the carbon calcining furnace shall be based on the elevation of the supporting plate surface of the calcining chamber frame.
The allowable range of the thickness of the brick masonry brick of the carbon calciner should be: 1mm~3mm for the calcination tank and the fire door cover, 2mm~4mm for the fire partition wall and the surrounding wall.
The inner and outer brick joints of the calcination tank shall be jointed with thick refractory mud before laying the cover bricks of each fire passage.
The inner surface of the calcined pot masonry shall not have a wrong tooth opposite to the discharge direction, and the forward tooth shall not exceed 2 mm.
The expansion joint between the calcination tank and the brick wall shall not be blocked, and the joint of the expansion joint with the fire passage shall be filled with materials such as refractory ceramic fiber.
The insulation of the roof and the refractory castable shall be applied after the end of the oven and after trimming.
The iron castings for each layer of temperature measuring holes, fire holes and slag holes in the rear part of the furnace body shall be installed with the building and shall not be refilled afterwards.
