Brick joint control tool used for fully laying carbon bricks on furnace bottom of blast furnace, and using method of brick joint control device

Abstract

The invention provides a brick joint control tool used for fully laying carbon bricks on the furnace bottom of a blast furnace and the using method of the brick joint control device. The brick joint control tool comprises a screw wedge and a screw support, the method used for fully laying the carbon bricks on the furnace bottom of the blast furnace comprises the following steps: during brick entering and pre-laying, using the screw wedge for wedge-caulking to the two ends of each carbon brick to be built in each row, during carbon brick laying, placing the screw support on the two sides of a brick in a center row so as to tightly prop the carbon brick to be built, removing the screw wedge, and removing the screw support. The brick joint control tool provided by the invention has the advantages that the material access is easy, the manufacturing is simple, brick joint control is convenient, and brick joint quality can reach the standard easily; adjustment can be performed arbitrarily, the probability of damage is low, and repeated and long-term cycle use is facilitated. Therefore, the laying quality is improved, and the construction progress is accelerated; and timber for manufacturing wooden wedges and the cost for purchasing screw jacks in the traditional process are reduced greatly, therefore, the construction cost is lowered, and economic benefits are improved.

Description

technical field [0001] The invention relates to a blast furnace masonry construction process, more specifically, the invention relates to a brick joint control tool for the blast furnace bottom full-paved charcoal brick masonry and its application method. Background technique [0002] At present, the newly-built blast furnace is generally more than 1,000 cubic meters and the bottom of the furnace is covered with large carbon bricks. The general size of the carbon bricks is 400mm high and 500mm wide, but the length varies. For the brick joint design of blast furnace masonry, the general design requirement is ≤1mm, and the requirements during the construction process are extremely strict. Therefore, whether the control of brick joints can reach the standard is an important guarantee for the construction quality and construction progress of blast furnace masonry. [0003] The masonry construction of the blast furnace bottom covered with charcoal bricks is divided into two part...

Problems solved by technology

However, since the screw jack in use is placed flat, it is not suitable to be fixed; and because its force after tightening is far less than 5 tons (each carbon brick weighs about 0.5 tons), it is easy to be damaged during use and turnover; In addition, the price of the screw jack is relatively high, and such use is also a waste of resources
