Description
Technical field
The utility model relates to the maintenance technique of mammoth conveter, relates in particular on a kind of mammoth conveter furnace lining and builds by laying equipment.
Background technology
At present, domestic mammoth conveter is with economical and practical and higher slag splashing technology, improves furnace life to prolong and repair stove stove labour and be the process for making of characteristics.Oxygen converter steelmaking is to carry out in the high temperature more than 1600 ℃, and converter shell inside must be built certain thickness refractory materials by laying bricks or stones as furnace lining, and furnace lining mainly is made up of working lining, permanent layer and packing layer three parts.Usually the structure according to the converter type of furnace is divided into furnace crown, shaft and furnace bottom three parts with furnace shell; Furnace crown is built by laying bricks or stones by magnesia carbon brick usually and is formed, and does not establish permanent layer and packing layer; Shaft is by working lining, and permanent layer and packing layer three parts are formed formation; Furnace bottom generally is made of working lining and permanent layer, and working lining is built by magnesia carbon brick and formed, and permanent layer is built by laying bricks or stones by the standard magnesia brick and formed.
The mode that converter lining is built by laying is according to the furnace type structure difference of converter, be divided into usually build by laying oven process and under build by laying oven process.In the past in the middle primary converter of our domestic design, the maintenance of the furnace lining of converter and building by laying is all adopted down and amended the law is main, this to the design requirements of converter than higher, converter body need be in the segmentation of the bottom of body of heater, need again the body stage casing and the hypomere of converter are provided with coupling device, therefore, the design of revolving furnace body is with regard to more complicated, and the life-span of converter is the all-in-one-piece life-span weak point of relative revolving furnace body also.In addition, also need to dispose the special stove truck system of repairing, output investment ratio is bigger.Comprehensive above two kinds of factors, such design is all relative unfavorable to the life-span of repairing stove and converter and the investment of mammoth conveter, while is along with the development of converter current steel-making Technology of Slag Splashingfor Furnace Maintenance, mammoth conveter average furnace life reaches 10181 stoves, Medium Converter average furnace life is 15298 stoves, and small vessel furnace life also reaches about 10316 stoves.Therefore, more and more adopt the stove mode of building by laying of repairing in the furnace system repairing of mammoth conveter.
The mode of repairing in the converter generally has: amend the law on converter is simple and easy, primary converter in the adaptation is its typical representative with the converter of 80T (ton)～200T (ton) Ma Gang, ripples steel, Wuhan Iron and Steel Plant; The simple and easy Lu Tashang of repairing of converter amends the law, and primary converter in the adaptation is its typical representative with the converter of the husky steel of 180T; Mammoth conveter is repaiied Lu Tashang and is amended the law, and adapts to mammoth conveter, with its typical representative of 300T converter Ma Gangwei; The stove mode of repairing of external mammoth conveter adapts to mammoth conveter, is representative with Wuhan Iron and Steel Plant three steel-making 250T converters and Baosteel 300T converter, is characterized in increasingly automated and mechanize, is equipped with complicated hydraulic efficiency system, and cost of equipment is very big.
The mode of repairing in these several converters, its comparative result can be referring to subordinate lists:
| On repair mode relatively | Amend the law on converter is simple and easy | The simple and easy Lu Tashang of repairing of converter amends the law | Mammoth conveter is repaiied Lu Tashang and is amended the law | The stove mode of repairing of external mammoth conveter is introduced |
| 1 | Weight of equipment is light, | Weight of equipment is light | Weight of equipment is heavy | Weight of equipment is heavy |
| 2 | Oxygen rifle vestibule crane is little, the steel construction less investment | Oxygen rifle vestibule crane is little, the steel construction less investment | Oxygen rifle vestibule crane is big, and the steel construction investment is many | Oxygen rifle vestibule crane is big, and the steel construction investment is many |
