Description
Technical field
The present invention relates to a kind of high-efficiency long-life safety rolling-wheel fixed casting machine that blast furnace ironmaking is used.
Background technology
Pig machine is the important corollary equipment of blast furnace, is that blast furnace is smelted the equipment that the molten iron that is cast iron block.Present rolling-wheel fixed casting machine mainly is made up of transmission device (comprising motor, reductor, drive sprocket, driven sprocket, chain belt and roller), monoblock type molten iron trough, cast iron quality pig mold, spray cooling device, last chain belt swage bottom cooling device, following chain belt swage bottom cooling device, fixed chute, iron block removal device, refractory gunning equipment, swage drying unit and residual iron gathering-device etc.Motor, reductor and drive sprocket place the chain belt of pig machine high-end, and chain belt is supported by roller, and driven sprocket places the chain belt low side of pig machine, and roller is fixed on the pig machine base.
The course of work of pig machine: every pig machine all is provided with two row's transmission chain belts, operation simultaneously.Pig mold is fixed on the transmission chain belt.The molten iron of hot-metal bottle is in molten iron trough flows into two row's pig molds of pig machine, molten iron is along with the transmission of chain belt is cooled to casting pig by the shower water on top gradually in the pig mold, after running to the terminal of chain belt, casting pig that solidifies and pig mold break away from, plough under in the blowpit, slip in the collecting cart along cell wall.The iron block that sticks to individually in the pig mold is removed by the iron block removal device.When chain belt returns, be arranged on the refractory gunning equipment of pig machine bottom, lime white is sprayed onto on the pig mold, prevent that iron block and pig mold from sticking together.The refractory gunning equipment bottom is provided with the pig mold drying unit, and the pig mold after the whitewashing is dried, and blasts because of the pig mold gunite layer contains moisture when preventing pouring molten iron.
In use there is following problem in existing pig machine:
Molten iron trough is a monolithic construction, and section is a rectangle, and molten iron trough and chain belt are in vertical direction.When hot-metal bottle was poured onto molten iron in the molten iron trough, molten iron splashed seriously, influenced the molten iron recovery rate of pig machine;
The pig mold material adopts common casting pig, vermicular cast iron or ordinary low-carbon steel, and the pig mold life-span is short.The unreasonable structure of while pig mold, internal stress is excessive in the use, and pig mold is damaged too early.More than two kinds of reasons to cause pig mold to change frequent, have a strong impact on the comprehensive production capacity of pig machine.
The whitewashing mouth of refractory gunning equipment very easily stops up in the whitewashing process; because refractory gunning equipment one end and feed pipe for mortar welding; one end is that bolt flange connects; therefore stop up the back mediation, change very difficulty; in case so refractory gunning equipment cisco unity malfunction; will cause normally a series of problems such as the demoulding of iron block, finally cause stopping accident, bring hidden danger for the safety in production of pig machine.
Pig machine does not have non-return device of chain belt at present.In case chain belt is in the course of work fracture that meets accident, chain belt will decline to low side from high-end, and in this case, pig machine will be subjected to badly damaged, can cause security incidents such as shutdown, stopping production.
