The large square hole cover is simple in structure, strong in corrosion resistance, good in thermal insulation effect, convenient to manufacture and long in service life, and the technical scheme is applicable to various large square hole covers of blast furnaces.
Description
Technical field
The utility model relates to the blast-furnace smelting field, and more particularly, the utility model relates to the generous port lid of a kind of blast furnace.
Background technology
Blast furnace is the major equipment of smelting iron and steel.Blast furnace carries out the layout blanking of furnace charge by distributor chute, and the big square hole of blast furnace is the passage of changing distributor chute.Blast-furnace smelting is to carry out under airtight state.After distributor chute is finished in replacing, need to seal with generous port lid.The generous port lid of blast furnace is in the top of blast furnace, is subjected to the corrosion of stove inner high voltage, high temperature and coal gas, and the generous port lid of blast furnace is yielding, wearing and tearing, leak, and work-ing life is short.
The utility model content
The purpose of this utility model is, provides a kind of blast furnace generous port lid, and this generous port lid is simple in structure, easily manufactured, cheap, corrosion-resistant, good heat-insulation effect, long service life.
For achieving the above object, the utility model has adopted following technical scheme:
The generous port lid of a kind of blast furnace, described generous port lid comprise and cover body 1, anchor nails 2 and refractory masses 3 that described anchor nails 2 is fixed on the internal surface that covers body 1, in described refractory masses 3 is coated on anchor nails 2.
Described anchor nails is V-structure or γ type structure, and those skilled in the art can select specification, the shape of anchor nails according to practical situation, reach the fixedly purpose of refractory materials.
The angle of described V-structure or γ type structure is 50 °～70 °, is preferably 60 °.
The height of described V-structure or γ type structure is 90～130mm, is preferably 110mm.
Determine the height of anchor nails according to the thickness (blast furnace is not of uniform size, and the height of generous port lid is also different) of the generous port lid of blast furnace, the height of anchor nails is near the thickness of generous port lid.
The making material of described V-structure or γ type structure is the round steel of Φ 6～Φ 8mm, is preferably Φ 6mm.
The thickness of described refractory masses is 100～140mm, is preferably 120mm.To cover anchor nails be requirement to the thickness of described refractory masses satisfying.
The making material of described refractory masses is the FN-130 spray material, and those skilled in the art can select the refractory materials (such as corundum castable) of close function to substitute this spray material, and reach identical purpose according to practical situation.
Described anchor nails 2 is fixed on the internal surface that covers body 1 by the mode of welding, also can adopt other fixed forms that anchor nails is fixed on the internal surface that covers body, is connected and fixed such as screw.
The generous port lid of the blast furnace that the utility model provides is gone up coating fire-resistant material by surface within it, reaches the effect of isolation.
The utlity model has simple in structure, characteristics such as erosion resistance is strong, cheap, good heat-insulation effect, easily manufactured, long service life.The generous port lid of this blast furnace can be used at the big square hole of any blast furnace, and may extend to other close industry, has applied range, the application value advantages of higher.
