Abstract
The utility model relates to a masonry structure of a 120-ton converter lining. The masonry structure comprises a converter body refractory material, a refractory material at a contact part between a converter body and a converter bottom, and a converter bottom refractory material and is characterized in that the thickness of each furnace block in the refractory material at the contact part between the converter body and the converter bottom is 100 to 110mm, and the lengths of lower layers of furnace blocks close to the direction of a hearth are sequentially increased by 50-70mm than upper layers of furnace blocks, and a stepped structure is formed by 5 to 7 layers of furnace blocks. The masonry structure has the advantages that that the refractory material at the contact part between the converter body and the converter bottom is transformed into be in stepped contact from direct contact, and the converter lining is corroded step by step in the production process of converters, so that a concave dead angle is hard to form and influence the quality of molten steel.
Description
Technical field
The utility model relates to a kind of masonry construction of 120t converter lining, belongs to the field of steel-making that metallurgical industry is produced.
Background technology
In the steelmaking production in metallurgical industry process, if take, converter produces soft steel as main, endpoint carbon content of converter is on the low side, so just cause converter lining to corrode serious, when shaft (furnace wall) is built by laying bricks or stones with the furnace lining employing vertical mode of furnace bottom seam crossing, after the refractory materials of converter molten pool furnace bottom and shaft seam region is corroded, there is the dead angle of indent, the fettling difficulty is large and affect steel quality.In addition, if frequent fettling affects the production direct motion, cause the output of converter molten steel lower.
According to the author who is published in " 2009 maintenance engineering company equipment and technology research papers integrate " wine steel science and technology monograph, introduce as Zhu Tongxi " 120 tons of converter masonry technology scheme optimizations ", the furnace wall of wine steel 120t converter and furnace bottom seam crossing adopt vertical mode to build by laying bricks or stones.
Utility model patent " a kind of mammoth conveter furnace bottom permanent liner refractory brick " (grant number CN201348442Y) according to the authorized application of the people such as Lv Ming by Laiwu in Shandong province Steel stock Co., Ltd is introduced, and the furnace wall of Laigang 120t converter and furnace bottom seam crossing adopt vertical mode to build by laying bricks or stones.
Summary of the invention
After being corroded, the fire proof material of furnace lining that the purpose of this utility model is to provide a kind of converter molten pool furnace bottom and shaft seam region do not have the masonry construction of 120t converter lining at the dead angle of indent.
The purpose of this utility model is realized by following mode:
The utility model comprises refractory materials, the bottom refractory of shaft refractory materials, shaft and furnace bottom contact site, it is characterized in that: in the refractory materials of shaft and furnace bottom contact site, the thickness of every stove brick is 100-110mm, lower one deck length by burner hearth direction stove brick increases 50-70mm than last layer brick successively, total 5-7 layer, form ladder-type structure.
The utility model has the advantage of: the refractory materials of shaft and furnace bottom contact site changes the staged contact into by original direct the contact, and furnace lining progressively corrodes in converter production process, is difficult for forming the dead angle of indent and the quality that affects molten steel.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to accompanying drawing, converter is by burner hearth 1, shaft 2, furnace bottom 6, and furnace lining forms, furnace lining is formed by the refractory-lined ovens brick masonry, furnace lining comprises refractory materials 4, the bottom refractory 5 of shaft refractory materials 3, shaft and furnace bottom contact site, and in the refractory materials of shaft and furnace bottom contact site, the thickness of every stove brick is 100-110mm, leans on lower one deck length of burner hearth direction stove brick than last layer brick, to increase 50-70mm successively, total 5-7 layer, form ladder-type structure.
Embodiment 1: the thickness of the every stove brick in staged contact site is 100mm, and lower one deck length of close burner hearth direction stove brick increases 60mm than last layer brick successively, has 6 layers.
Embodiment 2: the thickness of the every stove brick in staged contact site is 110mm, and lower one deck length of close burner hearth direction stove brick increases 70mm than last layer brick successively, has 6 layers.
The thickness of stove brick of building furnace lining by laying bricks or stones of the present utility model and near the length that lower one deck Length Ratio last layer brick of burner hearth direction stove brick increases be with this converter working condition under the MOLTEN STEEL FLOW state be complementary, under shaft and the rational thickness of place, furnace bottom contact site stove brick and length collocation condition, the consumption minimum of stove brick and the molten steel of converter smelting are difficult for producing dead angle, therefore are conducive to improve steel quality.
