Boya Precision Industrial Equipments Co. Ltd

We are offering knife and blade. Boya produces different kinds of blades for cutting strips, such as blades for rotary shear, blades for scrap cutter. Boya developed hard alloy blades and compound alloy blades which have well comprehensive properties. They are top level of technical in china. Their life is longer than other common blades. Especially suitable for cutting silicon steel strips, titanium alloy strips, and high-accuracy thin sheet, etc. This blades have been used in baosteel. Materials of our blades are supplied by well-known domestic or foreign steel companies. We choose material to produce them according to different performance requirements at different working situations.

Wea are offering constant velocity joint. Because the characteristics of high accuracy, constant speed, ease movement, long working life and so on, ball cage universal coupling is accepted by more and more customers. Both drum-gear coupling and cross shaft universal coupling can be substituted by ball cage universal coupling completely with its reliable capacity and high cost performance. This cv joint we manufactured is used in steel making, continuous casting, hot rolling and cold rolling in steel industry and performs very well. E.g. During the 11th five-year plan , boya provided more than 4000 ball cage universal couplings specially for over 20 production lines to baosteel. We also provide more than 400 sets of ball cage universal couplings to shougang shunyi steel mill at one lot. Ball cage universal coupling is also widely applied to driven system of leveler, mill and other equipments in non-ferrous industry. Boya gets many patents of ball cage universal coupling, such as short-type ball cage universal joint, ball cage clutch, large expansion ball cage universal joint and self-aligning ball cage consistent universal coupling, etc.

Boya manufactures spare parts for sendzimir mill, include work roll, the first intermediate roll, the second intermediate roll. Boya analyzes and researches the situation of rolls application. Based on the material of d2, m2 and h13, we developed a new kind of material, after been heat treatment its max surface hardness can be hrc67. It is improved in aspects of wear resistant, thermal shock resistant, anti-fatigue and accident resistant. It is applied in tai steel, luoyang copper, yongzheng stainless steel, jinwei copper, chunlei copper and zijin copper and has got good reputation. Main rolls include work roll, intermediate roll, rubber roll, etc.

We are offering pendular flying shear is used for cross-cutting strip in running process, such as cut the front of stripã??the weld root and etc. This pendular flying shear consists of the bases, transmission system, pendular cutting organ, feeding organ, lubrication system, the electrical control system, and pneumatic systems. Its mechanism and action principle are as follow: the bases are large welding part, which can bear the weight of transmission system, pendular cutting organ, strip-oriented and compaction organ. The transmission system mainly consists of the main motor, primary speed reducer, fly wheel, brake, coupling, clutch, secondary speed reducer and etc. The pendular cutting organ consists of the initiative crankshaft, initiative frame, driven crankshaft, and initiative sw(swiss wisit). The whole initiative frame (with fixed blades on it) drives the driven crankshaft at the same time when swings with the initiative crankshaft. The initiative sw(with movable blades on it) drives the unfixed blades in an up-down direction to conduct cross-cuts on the steel strip when swings with the driven crankshaft. The feeding organ is designed at the cutting exit, where roller is driven by the air cylinder to compact the front of strip after cutting, and at the same time guide them to up-work station or down-work station. This flying shear takes the material from the right side, with a maximum synchronous cutting speed of 180m/min technological parameters of the strip: yield strength ï?sâ?¤260mpa width 500~1100mm thickness 0.15~0.6

we are offering Tension Leveler. BY type tension leveler is finishing equipment for galvanizing line, tinning line, aluminum line, color coating line, level and recoil line, it formed by: leveler body, bridle rolls at entrance and exit, power transmission system, roll change car, hydraulic system, electrical control system. . BY type tension leveler is suitable for leveling common carbon steel, stainless steel or non-ferrous metals. Its highest working speed can reach up to 450m/min. the strip specification can be: width: 550-1630mm, thickness: 0.1-4mm. . There are six types of BY tension levelers, three types are strip entry into the leveler from right side, and other three types are strip entry into the leveler from left side. The structure of them are one bending and one leveling, two bending and one leveling, two bending and two leveling . There are about 130 sets tension levelers produced by BOYA service for domestic market and abroad market, like: Hengshui Strip Rolling Co., Ltd, jianyin Comat Metal Products Co., Ltd and etc. . The descaler manufactured by BOYA have export to abroad market, and 1450 type descaler will be service for China Baosteel.

We are offering shear. The circle shears designed and manufactured by boya are used for trimming and slitting strips, they are active shears type and driven shears type, they own tree types in contracture like twin town type, cantilever type and shaft type. There are about 20 set shears made by boya service for steel and non-ferrous industry at present. Materials: common carbon steel, stainless steel, silicon steel, titanium alloy steel, nickel-chromium steel, aluminum steel, copper alloy and etc. Materials thickness:0.08-5.0mm maximum speed of circle shear: 500m/min, product width: 3-5 mm parameters of circle shear: radial run-out of blade shaft: â?¦0.01mm axial run-out of blade shaft: â?¦0.005mm face run-out: â?¦0.003mm parallelism of blades shafts: â?¦ 0.01mm overlap: â?¦ 0.02mm patents our circle shear have got: change blades swiftness patent wide strip edge cutting patent.
