Problems solved by technology

In the hot continuous rolling walking heating furnace, the existing walking heating furnace beam and column anchor hooks are L-shaped, the strength is low, and the material is 1Cr18Ni9ti, which has poor high temperature resistance and oxidation resistance, so the high temperature walking heating furnace The service life of beam and column refractory materials has always been low, and the shortest actual service life is only about three months. The shedding of the heat insulating refractory materials of the beam and column of the heating furnace seriously affects the heating quality of the heating furnace slab and the cooling water consumption of the heating furnace. Gas consumption, and affect the maintenance cycle of the heating furnace

Abstract

The present invention is beam and column for walking heating furnace and their construction process. The column includes core pipe, water pipe, anchor hook, fiber blanket and cast layer; and the beam includes water pipe, anchor hook, heat resisting spacer block, fiber blanket and cast layer. The beam and the column feature the fiber blanket capable of resisting high temperature up to 1250 deg.C, the Y-type anchor hook of stainless steel capable of resisting high temperature up to 1050-1150deg.C and coated with asphalt paint, and the cast layer of material with cured strength not lower than 90 MPa at 1400 deg.C. The construction process of the beam and the column includes the steps of welding anchor hook, coating fiber blanket, assembling formwork, casting, demolding and stoving. The beam and the column have high strength, high heat resistance, good antioxidant performance and long service life.

Description

technical field [0001] The invention relates to a beam and column of a walking heating furnace and a construction method thereof. Background technique [0002] Heating equipment is the dominant equipment in the metallurgical industry. The service life of refractory materials used in heating equipment directly affects the production capacity and heating cost of the heating furnace. In the hot continuous rolling walking heating furnace, the existing walking heating furnace beam and column anchor hooks are L-shaped, the strength is low, and the material is 1Cr18Ni9ti, which has poor high temperature resistance and oxidation resistance, so the high temperature walking heating furnace The service life of beam and column refractory materials has always been low, and the shortest actual service life is only about three months. The shedding of the heat insulating refractory materials of the beam and column of the heating furnace seriously affects the heating quality of the heating f...
