Method for controlling molten steel processing of steelmaking workshop

The invention relates to a method for controlling molten steel processing of a steelmaking workshop. Process constraints in actual production are taken into account to reduce heat losses of molten steel and obtain a process for controlling the molten steel processing of the steelmaking workshop. By adopting the method, prompt production can be achieved, the times of interruption to casting can bereduced, the rate of utilization of production equipment can be increased, the production of a steelmaking plant can be carried out according to the processing startup time of heat on each machine, and the heat can be promptly delivered to a continuous casting machine to ensure continuous casting. Meanwhile, the load on each refining device is uniform, the failure rate is low, and the productivity of the continuous casting machine and the steelmaking workshop can be improved. By adopting the method, new production schemes can be prepared in a short term according to new production environments so as to deal with unavoidable equipment faults and other unexpected accidents. Due to the reasonable and efficient control of the molten steel processing progress, the heat can be utilized on the reasonable machine, excessive heat delivery can be reduced, energy can be saved, the logistic cost can be decreased, the waiting time of molten steel in different procedures and heat losses of the molten steel can be reduced, and the effects of energy conservation and consumption reduction can be achieved.

Carbon fiber or carbon crystal electric heating floor capable of being cut at random and mounted conveniently, and use method

The invention relates to the field of electric heating floors, in particular to a carbon fiber or carbon crystal electric heating floor capable of being cut at random and mounted conveniently, and a use method. The carbon fiber or carbon crystal electric heating floor solves the problems that the existing electric heating floor cannot be cut at random, and has a larger cold edge and the like. A carbon fiber electric heating core or a carbon crystal electric heating core is located between a composite floor backboard and a composite floor panel; wiring holes are formed in the composite floor backboard; power supply anode connecting lines and power supply cathode connecting lines penetrate through the wiring holes respectively and are connected to an electrode in the carbon fiber electric heating core or the carbon crystal electric heating core; independent heating areas of the carbon fiber electric heating core or the carbon crystal electric heating core are heated respectively or simultaneously; the carbon fiber electric heating core or the carbon crystal electric heating core is carbon fiber heating paper or in a carbon crystal heating paper and electrode composite structure; the carbon fiber heating paper or the carbon crystal heating paper is divided into two or more independent heating areas; and the independent heating areas are connected into a whole by the electrode. Therefore, the floor can be cut transversely and vertically, and the scope within the cold edge meeting the specification is the heating area.

Shredding device for maize harvesting machine impurity removal draught fan

The invention relates to a shredding device for a maize harvesting machine impurity removal draught fan. The shredding device comprises a discharging opening, a bolt, a nut, a gasket, a fan blade seam, a draught fan shell seam, an axle nut, an axle gasket and a shredding blade. The discharging opening and the fan shell seam are connected through the bolt, the nut and the gasket. The fan blade seam is installed inside the fan shell seam. The fan blade seam is composed of four rotating vanes, four rotating blades and a rotating shaft, the four rotating vanes are uniformly arranged on the rotating shaft in the circumferential direction, the four rotating blades are installed on the four rotating vanes respectively, one end of the rotating shaft penetrates through a lower flange in the fan shell seam to be connected with a motor, the other end of the rotating shaft is provided with the shredding blade, and the shredding blade is fixed through the axle nut and the axle gasket. Due to the fact that maize straw and other impurities are cut through the shredding blade and the rotating blades two times, particles become finer and smaller, the field returning effect is better, the impurity removal draught fan is not likely to be blocked, the number of impurities entering a peeling machine is small, the service life of the peeling machine is prolonged, and economic benefits are created.

Liquid fuel gasification combustor suitable for mixed alcohol oil and capable of achieving complete combustion

The invention relates to a liquid fuel gasification combustor suitable for mixed alcohol oil and capable of achieving complete combustion. The liquid fuel gasification combustor suitable for mixed alcohol oil and capable of achieving complete combustion comprises a plurality of gasifier heads, an ignition mechanism, a fuel supply system, an air duct, an air valve and a fan. The liquid fuel gasification combustor is electronically controlled and can be started in a one-click mode to operate automatically. In use, the air duct is divided into an intra-furnace air duct part and an extra-furnace air duct part according to the position relationship with a boiler. An air-oil mixing box is embedded in the top surface of the intra-furnace air duct part. The gasifier heads are evenly and fixedly mounted in the air-oil mixing box at intervals. An oil supply pipe is connected to the bottom of each gasifier head. The oil supply pipes are led out through the air duct and connected with the externalfuel supply system. The ignition mechanism is mounted above the air-oil mixing box and located on the side close to the extra-furnace air duct part. According to the liquid fuel gasification combustor suitable for mixed alcohol oil and capable of achieving complete combustion, the multiple gasifier heads are mounted in the air-oil mixing box so that multiple burners can be ignited at the same time; and in addition, fuel oil which is not completely combusted can be stored in the air-oil mixing box so as to be combusted for the next time, so that waste is avoided, and the oil utilization rate of the liquid fuel gasification combustor is far higher than that of common combustors on the market.
