Cutting separation method for high furnace base under production state

Abstract

The invention discloses a cutting and separation method of a blast furnace foundation under a production status, which is characterized in that the production method comprises the steps: A. drilling, a plurality of parallel horizontal through holes are arranged at the middle and upper part of the blast furnace foundation side by side; B. cutting, a cutting unit and two neighboring through holes are chosen, and by taking advantages of cutting equipment, the foundation of the blast furnace is cut in horizontal between the two neighboring through holes; C. filling, a pressure bearing isolation layer is arranged in the cutting seam; D. the step B and C are repeated until all neighboring through holes are well provided with the pressure bearing isolation layer; E. brackets are arranged at two edges of two sides of the pressure bearing isolation layer, the two side brackets are used as the neighboring through-holes of the edge through-hole, and the step B and C are repeated. The cutting and separation method of the blast furnace foundation of the invention operates the blast furnace foundation cutting to lead the blast furnace and the foundation to be separated under the conditions of no effect of the blast furnace production status and in order to shorten the blast furnace repairing time. The method can shorten the blast furnace repairing time for about 2 to 3 months.

Description

Technical field: [0001] The invention relates to the field of blast furnace repair, in particular to a method for cutting and separating blast furnace foundations in a production state. Background technique: [0002] In iron and steel production enterprises, when the blast furnace needs to be overhauled, it is necessary to keep the blast furnace foundation and replace the blast furnace body. In the prior art, the method of breaking the blast furnace body is usually used, and some more advanced enterprises cut and separate the blast furnace foundation, but in the prior art These methods all need to shut down the furnace, and this method takes a long time, usually 2 to 3 months, so it needs to bear the economic loss caused by the shutdown. Invention content: [0003] An object of the present invention is to provide a method for cutting and separating blast furnace foundations in a production state, using the method, the cutting and separation of blast furnace foundations can...
