Adopting this utility model of technique scheme, compared with prior art, it provides the benefit that:
By regulating flow and wind pressure device, it is possible to the hot blast parameter of all blowpipes is regulated consistent, efficiency and the molten steel quality of blast furnace will be greatly improved, reduce energy resource consumption；Multiple-insulating heat insulation structural can effectively improve the hot blast temperature sending into blast furnace, reduces thermal losses and saves the non-renewable energy resources such as coal, reduce the temperature of blowpipe outer surface, improve operating environment, reduces CO2Deng disposal of pollutants, protect environment purpose.
As preferably, this utility model further technical scheme is:
Pressure tester includes pressure-measuring pipe and lower pressure-measuring pipe.The blast of the internal hot-air channel of blowpipe can be accurately measured by two or more pressure point.
Upper pressure-measuring pipe and lower pressure-measuring pipe respectively by outside bend pipe and sequentially pass through metal box hat, the hot-air channel of multiple-insulating heat insulation structural is constituted, hot-air channel is built molding by refractory material, it is positioned at outside outside metal box hat one section of hot-air channel and wraps up in steel thimble, steel thimble one end is welded with metal box hat, and the other end is connected with bend pipe by flange.
Steel thimble is two-part structure, and a section welded with metal box hat is major diameter sleeve pipe, is minor diameter sleeve pipe with the one of Flange joint section, and minor diameter sleeve pipe and major diameter sleeve pipe joint portion are equipped with connecting plate.More refractory matter can be poured into a mould, to improve thermal and insulating performance in major diameter sleeve pipe.
The valve body of flow regulator is assemblied on metal box hat by flange assembly, and the spool of flow regulator is high temperature resistant goods, by adjusting the air quantity of the internal hot-air channel of spool angular adjustment blowpipe.
Multiple-insulating heat insulation structural is inwardly followed successively by the insulation refractory casting bed of material, stainless (steel) wire compartment, corundum castable inner liner, antiradiation wear-resistant liner layer from the medial wall of metal box hat.The insulation refractory casting bed of material plays the effect reducing external skin temperatures; stainless (steel) wire compartment plays to be protected when building corundum castable inner liner lightweight refracrory not destroyed and merges the effect of refractory material; heat can be reduced hull-skin temperature to hot blast channel reflection by antiradiation wear-resistant liner layer; prevent heat losses; improve and send into in-furnace temperature, improve the erosion resistibility of resistance to material.
