Embodiment Construction

[0020] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0021] A method for building refractory bricks for a mixed-iron car according to the invention utilizes the characteristic that the drum-shaped tank body 1 of a mixed-iron car can rotate around the trunnion 2, and builds refractory bricks 4 in sections along the radial direction of the tank body, so that the ground work is always maintained , the order of construction is as follows:

[0022] 1) see figure 1 Place the tank mouth 3 of the mixed iron truck upwards, build refractory bricks 4 along the inner wall of the tank body 1 to a position 200-300 mm above the center line of the tank body, and complete the refractory bricks on the end walls 5 on both sides ;

[0023] 2) see figure 2 , set the hard miscellaneous wood 6 along the stop end of the refractory brick that has been built, use the push rod 7 to withstand the hard miscellaneous wood 6,...

Abstract

The invention relates to a construction method of torpedo hot metal mixer car fireproof bricks, which is characterized in that by using a characteristic that a barrel-shaped pot body of a torpedo hot metal mixer car can rotate around an ear shaft, the fireproof bricks are constructed in partition regions and operation can be kept on the ground. The construction sequentially comprises the following steps: 1) constructing the fireproof bricks till up to a position being in 200-300mm height above the central line of the pot body in the pot body along the inner wall of the pot body, and constructing the fireproof bricks on end walls at two sides; 2) arranging mixed hardwood along the stop end of the fireproof bricks, and fixing the stop end of the fireproof bricks along the length direction; 3) rotating the pot body by 90 degrees, and constructing an A area after the rotation; 4) arranged mixed hardwood along the stop end of the fireproof bricks of the A area, and fixing the stop end; and 5) continuously rotating the pot body by 180 degrees, and constructing a B area. Compared with the prior art, the construction method has the beneficial effects that 1) springboard and a mold erection for aloft work are avoided, so that the operation is convenient and is high in efficiency, and the labor intensity of workers can be greatly reduced; and 2) the construction quality of the fireproof bricks can be reliably ensured, and the utilization rate of a torpedo hot metal mixer car and the safe running of devices can be improved.

Description

technical field [0001] The invention relates to a masonry method for lining refractory bricks in a mixed-iron wagon-type furnace body. Background technique [0002] At present, the development of mixed iron cars in China is very rapid and has been widely used. The masonry quality of refractory bricks lining the tanks of mixed iron cars affects the utilization rate of mixed iron cars and the safe operation of equipment, and also affects the economy of enterprises. benefit,. The tank body of the mixed iron car belongs to the large-scale cylindrical furnace body. The traditional arched furnace lining masonry process is to firstly build the lower half, and then set up a springboard as a working platform, fix the arched tire mold on the platform, and fill the tire mold. Refractory materials to achieve the desired shape of the lining. [0003] The tank body of the mixed iron car is composed of the tank body trunnion, cylinder body, tank mouth and refractory bricks. The whole tan...
