Description
The technical field is as follows:
the invention relates to a demoulding device, in particular to a surface flame demoulding device of a Hatzrett casting machine.
Background art:
the Hatzerland double-belt casting machine mainly comprises a metal melt supply device, a casting nozzle, two endless steel belts (an upper belt and a lower belt) running in parallel, two flange chain blocks, an upper frame, a lower frame, a steel belt supporting roller, a cooling system, an outlet pinch roller, a transmission control system and the like. Two endless steel belts are respectively tensioned on the tensioning rollers of the upper frame and the lower frame, and the downstream tensioning rollers play a role in driving and guiding. The upper frame can be lifted by the hydraulic lifting device, so that the steel belt can be replaced conveniently and equipment can be maintained conveniently. Two parallel steel belts and the flange chain block form a continuous casting die cavity.
In the aluminum liquid casting process, the endless steel belt of the Hatzlite double-belt casting machine plays a role in cooling the aluminum liquid, and the surface of the steel belt needs to be treated so as to improve the surface condition of a casting mould steel belt and avoid the adhesion of the aluminum liquid and the steel belt and the influence on the surface quality of a continuous casting aluminum plate. The traditional processing mode is as follows: in the processing and treatment process of a steel strip, the steel strip is subjected to surface sand blasting treatment by sand blasting with different materials and different particle sizes, generally graphite powder coating is sprayed, and the problem is that after the steel strip is used for a long time, the graphite powder coating is locally consumed, so that the local surface quality of an aluminum plate is unqualified; the other method adopts electrostatic spraying, wherein silicon dioxide powder in a powder tank is conveyed into a spraying device by two conveying pumps, the powder is sprayed out from the spraying device, all the powder is positively charged at an outlet along with high voltage of 12000V and is adsorbed on a steel belt, redundant powder is brushed off by a dust removing brush, and the brushed-off dust is collected in a dust collection chamber and is uniformly discharged. There are problems in that: 1. faults suddenly occur in the production process, the processing cannot be carried out, the quality of the plate strip is affected, the machine halt is caused by serious persons, and the hidden danger of production and the hidden danger of equipment safety exist; 2. the maintenance cost of the whole system is quite large, and the purchasing period of accessories is long; 3. the uniformity of spraying is very close to the temperature change, the change of the environmental temperature can cause the change of the spraying effect, the actual situation is difficult to grasp in production, and the control of the ambient temperature is difficult to realize; 4. the local powder amount appearing in the production is uneven, manual powder wiping is used for compensating, the control precision is poor, the labor amount is increased, the control precision is poor, and waste products are easy to produce.
The invention content is as follows:
in order to solve the technical problems, the invention aims to provide a surface flame demolding device for a Hatzerlott casting machine.
The invention is implemented by the following technical scheme: the surface flame demoulding device of the Hatzlette casting machine comprises two endless steel belts which are arranged on an upper frame and a lower frame and run in parallel, a casting cavity is formed between the two endless steel belts, the surface flame demoulding device further comprises two gas pipes which are horizontally arranged at the upper part and the lower part of the outlet end of the casting cavity, the two gas pipes are respectively fixedly connected with the upper frame and the lower frame, a plurality of burners are uniformly arranged on the gas pipes, and the burners face the steel belts.
Furthermore, each burner is provided with an adjusting valve.
When the device is used, liquefied natural gas is introduced into the gas pipe, the opening and closing and the flow of the burner are manually adjusted by observing the surface condition of the aluminum plate, and the liquefied natural gas is ignited for combustion after the burner is opened, so that the surface of the steel strip is coated with carbon black, and the steel strip is isolated from being in contact with the aluminum plate.
The invention has the advantages that:
according to the invention, the gas delivery pipe and the burner are arranged, the liquefied gas is utilized to be insufficiently combusted, the generated carbon black is uniformly coated on the surface of the steel strip, the carbon black is adhered to the surface of the steel strip, the molten aluminum is cooled by water after passing through the casting cavity and becomes solid, a diaphragm object is arranged between the steel strip and the aluminum plate, and the transmission is carried out through the transmission device, so that the aluminum plate and the steel strip are conveniently separated, the adhesion to the steel strip is avoided, the service life of the steel strip is prolonged, and the quality of the surface of the steel strip is ensured.
