Problems solved by technology

[0002] Refractory materials are widely used in cupolas, intermediate frequency furnaces, transfer ladles, etc. in the traditional casting and smelting industry. The traditional furnace building process is more complicated, and the construction is more troublesome. The finished product contains impurities, and at the same time, it is easy to crack after long-term high temperature. Stratification occurs, which affects the service life of the furnace body, and a new refractory material furnace construction process is urgently needed to solve the existing problems

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the examples.

[0023] A kind of oven construction technique, comprises following process step:

[0024] (1) Furnace building: cleaning and preparation before furnace building:

[0025] 1) Cleaning in front of the furnace: After the front of the new furnace or the old furnace is dismantled, clean the inside of the furnace and keep it tidy. It is necessary to check whether the coil is deformed, whether the cooling water circuit is smooth, and whether the power supply is normal. The new furnace should be dried and removed Moisture makes it dry, and at the same time, the working site of the electric furnace needs to be kept clean to prevent impurities from being brought into the furnace or mixed into the furnace lining material;

[0026] 2) Production of crucible: use a thin iron plate to make a tapered crucible. The thickness of the thin plate is determined by the tonnage of the electric ...

Abstract

The invention relates to a drying oven building process. The process comprises the following process steps of (1) building a furnace; (2) drying the furnace; (3) starting the furnace for smelting; (4)culturing the furnace; (5) discharging molten iron from the furnace for the first time; and (6) starting the cold furnace. The drying oven building process has the characteristics of high fire resistance, good slag resistance, stable high-temperature volume, wear resistance, scouring resistance and simple and convenient construction operation, and particularly has the environmental protection feature of being small in generated solid waste during use.

Description

technical field [0001] The invention relates to the technical field of furnace building with refractory materials, in particular to a furnace building process. Background technique [0002] Refractory materials are widely used in cupolas, intermediate frequency furnaces, transfer ladles, etc. in the traditional casting and smelting industry. The traditional furnace building process is more complicated, and the construction is more troublesome. The finished product contains impurities, and at the same time, it is easy to crack after long-term high temperature. Delamination occurs, which affects the service life of the furnace body, and a new refractory material furnace construction process is urgently needed to solve the existing problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oven construction process. [0004] In order to solve the above technical problems, the technical solution provided by the pr...
