| Advantages and specifications of medium frequency tube expander
Medium frequency pipe expanding machine is a kind of processing method of steel pipe. Medium frequency pipe expanding machine is one of pipe fitting equipment to process small caliber steel pipe into large caliber steel pipe.The mechanical properties of hot-expanded steel tubes are slightly worse than those of hot-rolled spiral steel tubes.Limited to the steel seamless steel pipe specifications are limited, according to the needs of the end consumer so hot expansion pipe expansion machine is produced.The specifications and models of the thermal expansion steel pipe are relatively large, and they are generally made according to the needs of customers. The thermal expansion steel pipe is the thermal expansion pipe that we often say. The steel pipe with low density but strong shrinkage can be referred to as the thermal expansion pipe.
At the same time, compared with other tube expanding machine series, the medium frequency tube expanding machine is controlled by the PLC induction system and has the function of automatic constant temperature, which reduces the labor cost and improves the production efficiency and appearance quality of the product.For the enterprise profit is possible, but also for customers in the steel pipe industry has made a huge contribution.
Medium frequency pipe expander is a kind of pipe fitting equipment and pipe fitting machinery of hot expanding steel pipe.It has the characteristic of automatic constant temperature.It is widely used in heavy industry, military aerospace and nuclear power industry of customers, so the demand is relatively large in the market.Seamless steel pipe according to the production process classification, is according to the way of processing and forming points, can be divided into hot rolled pipe, cold drawn pipe, cold rolled pipe.Thermal expansion should be a process in hot rolling.
From the appearance: cold drawn seamless tube length is generally shorter than the hot rolled seamless tube.The wall thickness of cold-drawn seamless tube is even than that of hot-rolled seamless tube.Cold drawn seamless tube is more uniform than hot rolled seamless tube wall, and the outer wall is more smooth and beautiful, hot rolled seamless tube is generally longer than seamless steel tube.
The middle frequency pipe expander concentrates the diameter expanding technology, the middle frequency induction heating technology and the hydraulic technology in the same equipment, the market efficiency is high, the energy consumption is small, the product produced is high quality.Medium frequency pipe expander can be said to be a hot pipe fitting equipment in recent years.
Our company mainly produces and manufactures medium frequency pipe expander according to the models customized by customers. With many years of manufacturing experience, the medium frequency pipe expander has a complete range of models, quality assurance and affordable prices
In this paper, the quality problems of large diameter seamless steel tube in pipe expanding unit are discussed, and several sizing forms are compared, and the advanced two-roller separate DC motor drive belt rapid roll change sizing machine and the sizing process of large diameter seamless tube in thermal expanding unit are analyzed.In full consideration of hot galvanizing temper mill production process characteristics, on the basis of both the strip shape quality of products and the stability of the formation process of zinc layer and the uniformity of zinc flower, exported strip before tension and rolling pressure transverse distribution is uniform as objective function, established a set for hot galvanizing temper mill elongation and before and after tension core process parameters, such as automatic integrated setting model, and apply it to the 1800 cold rolling mill ^ 3 # CGL hot galvanizing temper mill parameter Settings.
Pipe-expanding machine automatic control of intermediate frequency power supply at the time of expanding production will steel tube heated to the required temperature and constant, effectively avoid the human factors caused by the steel tube under the high temperature of steel pipe products and mold scrapped, and to avoid the low temperature and the thermal expansion unit increased thrust rod or die fracture phenomenon, caused by refusing to instability.Compared with manual operation, the steel tube is heated, which saves energy and health, simplifies the operation procedure and reduces the labor cost. It can make one operator at most simultaneously monitor the normal production and expansion of multiple tube expanding units.Each unit is equipped with two temperature measuring points for automatic temperature control.According to the preset heating temperature of different grades of steel tubes, the heating temperature of the steel tubes to be expanded can be selected and kept constant, and it can be displayed and recorded in real time, and the real time curve and historical curve of heating parameters can be printed and saved.Provide guarantees for data traceability.
Pipe expanding machine can expand the type of steel pipe: seamless steel pipe, spiral welded pipe, straight seam welded pipe.Pipe varieties are: provide, alloy steel, stainless steel and so on.
