A vertical continuous annealing furnace refractory material, lining installation method and movable installation platform

Abstract

The invention relates to a vertical continuous annealing furnace refractory material and lining installing method. The method includes the following steps that a movable installing platform is manufactured; the movable installing platform is hung and placed on a steel structure beam at the top of a vertical annealing furnace; construction workers stand in hanging baskets and perform construction from bottom to top, and anchoring nails and bolts can be simultaneously welded to the two sides of the furnace body and fiber board refractory material and stainless steel lining plates can be simultaneously installed on the two sides of the furnace body through the hanging baskets on the two sides; construction is carried out from one end to the other end in the furnace, and the movable installing platform can be hung and placed onto another technological segment through a bridge crane for construction. The invention further relates to the movable installing platform. The movable installing platform comprises the electric hanging baskets, a beam shaft, a beam, walking wheels, a chain block mechanism and a pulley mechanism. Compared with the prior art, the method has the advantages that the refractory material and linings of all the technological segments can be installed and constructed through the movable installing platform, the two sides of the same technological segment can be simultaneously constructed, the movable installing platform is simple in structure and convenient to install and operate, construction speed can be increased easily, and labor intensity and construction cost can be reduced easily.

Description

technical field [0001] The invention relates to a large-scale furnace body refractory material and a lining installation method, in particular to a vertical continuous annealing furnace refractory material, a lining installation method and a movable installation platform. Background technique [0002] The vertical continuous annealing furnace has now been widely adopted by the cold rolling mills of iron and steel companies as one of the core equipment for the production of high-quality steel plates in the continuous production line. The vertical continuous annealing furnace is mainly composed of various process sections such as preheating section, heating section, soaking section, slow cooling section, fast cooling section, overaging section, final cooling section and water quenching section. The total length of the annealing furnace (from the pre- The hot section—water quenching section) is about 170m, the furnace top elevation is about 33m, and the furnace body is about 3m...

Problems solved by technology

The traditional construction method is to lay thick wooden planks to protect the furnace bottom in each section of the annealing furnace, and then set up a full scaffolding on the wooden planks for construction. This method can meet the construction needs, but there are many disadvantages. There are more materials, which increases the cost of measures; second, after the construction of one process section, the scaffolding needs to be dismantled and transported to another process section for re-erection, which increases the workload and working time, and it is easy to scratch the construction when removing the scaffolding Finished refractories and linings are not conducive to the protection of finished products
