Description
Technical field
A kind of RH refining furnaces lower channel is the utility model is related to, knot is built by laying bricks or stones more particularly, to a kind of RH refining furnaces lower channel
Structure.
Background technology
Known, RH refining furnaces are a kind of secondary refining process equipments for being used to produce high-quality steel, and whole molten steel is metallurgical anti-
Should have in the vacuum tank of refractory lining to carry out in block, because lower channel service life is short, RH refining furnace lower channel refractory materials
Consumption is larger, especially for some not with the resistance to material of steel contacts it is no it is damaged in the case of just remove, waste is larger,
The discarded object disassembled simultaneously also causes very big pollution to environment.
RH refining furnace lower channels share four layers of refractory material and formed, and are respectively：Working lining, permanent layer, heat-insulation layer and silicic acid
Calcium flaggy.According to apart from molten steel distance, each position service life of refractory material is also different, so causing part brick not having
Just it is removed in the case of having breakage, causes the larger waste of resistance to material.Working lining deteriorates more due to directly being contacted with molten steel
Seriously, furnace life is shorter；Due to not contacted with molten steel, furnace life is longer for permanent layer, heat-insulation layer and calcium silicates flaggy, and half a year can be used extremely
1 year as long as.The masonry construction used at present is that upper position sets a brick plate among lower channel, and the resistance to material of lower channel is divided into
Lower two half parts, top half operational layer brick because away from molten steel, service life is longer, when changing the resistance to material in the latter half due to by
Drag the support top half of brick plate not have to change, reduce the consumption of resistance to material, but such a masonry construction of resistance to material is still not
The usage amount not with the resistance to material of top half permanent layer and heat-insulation layer of steel contacts can be effectively reduced, so as to cause the resistance to material in the part
Just it is removed, wastes larger in the case of no breakage.Existing RH refining furnaces lower channel masonry construction as shown in Figure 1,
Working lining support brick A1 bottom is welded with a circle gusset A2, for supporting whole top half operational layer brick；Permanent layer 3 and heat-insulation layer
A4 is built by laying bricks or stones in support brick A1 top, though the replacing number for reducing gusset above operational layer brick is so can guarantee that, with use
The increase of stove number, operational layer brick, which corrodes, to be accelerated, and residual thickness can not meet just to need to disassemble the part operational layer brick during use demand；Due to
The permanent layer 3 and heat-insulation layer A4 of the first half are built by laying bricks or stones on working lining support brick A1, so the part permanent layer 3 and heat-insulation layer A4 are resistance to
Material is just disassembled in the case of also without breakage, causes larger resistance to material to waste, while the discarded object disassembled also is made to environment
Into very big pollution.
The content of the invention
In order to overcome the shortcomings of in background technology, knot is built by laying bricks or stones the utility model discloses a kind of RH refining furnaces lower channel
Structure, by being provided with gusset B on the step on support brick B tops, top permanent layer brick and heat-insulation layer are sequentially provided with gusset B top
B, realizes top permanent layer brick and heat-insulation layer B reaches synchronous with the life-span of bottom permanent layer brick and heat-insulation layer C, reduces resistance to material
The purpose of waste.
In order to realize the goal of the invention, the utility model adopts the following technical scheme that：
A kind of masonry construction of RH refining furnaces lower channel, including support brick B, operational layer brick, heat-insulation layer B and heat-insulation layer C, under
The middle part of portion's groove is provided with inverted support brick B, the support brick B and is divided into lower channel two layers up and down, the inverted bottom for holding in the palm brick B from
It is interior to be provided with gusset B on the step on support brick B tops to operational layer brick, bottom permanent layer brick and heat-insulation layer C is sequentially provided with outside,
Gusset B top is sequentially provided with top permanent layer brick and heat-insulation layer B.
The masonry construction of described RH refining furnace lower channels, the heat-insulation layer B, heat-insulation layer C are correspondingly arranged, are being incubated up and down
Layer B, heat-insulation layer C outside are provided with box hat.
By adopting the above-described technical solution, the utility model has the advantages that：
The masonry construction of RH refining furnaces lower channel described in the utility model, lower channel is divided into by inverted support brick B
Upper and lower two layers, when disassembling top half working lining with regard to without being removed to its permanent layer brick and heat-insulation layer brick, making top forever
Long layer brick and heat-insulation layer B have reached synchronous with the life-span of bottom permanent layer brick and heat-insulation layer C, while also assures that lower channel works
Layer brick normally matches pattern with dipping tube lifetime, has saved the energy, has reduced the waste of resistance to material, suitable for split type RH stoves.
