Abstract
The present invention has provided a kind of preparation method of protecting tube.It is finished by the batching of selecting materials, fusing, casting drawing, butt and processing silk mouth, its described casting drawing is to adopt vertical casting, and at casting gate with electrode carbon-point insulation, on one side casting, drawing on one side, vibration on one side, the temperature of its electrode insulation is 1400 ℃-1450 ℃, treats during drawing that the blind capitiform of product becomes the back drawing, and the temperature of product drawing end is 900 ℃-1000 ℃ during drawing, drawing speed is 90-100 centimetres of per minutes, and the drawbench vibration frequency is per minute 50-60 times.It can not only improve speed of production, and can improve the finished product rate significantly.
Description
The present invention relates to a kind of preparation method of protecting tube.
Protecting tube is a kind of elongated blind hole cast iron pipe, and it is fixed on the inside in the mode of internal sealing plug with thermocouple, to prevent pernicious gas, the thermal etching destruction to thermocouple, plays the effect of protection thermocouple.The production method of existing protecting tube is to adopt the traditional handicraft of sand casting; it is cast with horizontal sandbox; at the bottom of its surface smoothness; the easy off-centre of product and concentricity is not up to standard; and the internal structure pore is many; general performance is low in yield rate, generally have only about 20 percent, and speed of production is slow.
The object of the present invention is to provide a kind of preparation method that can significantly improve the protecting tube of product quality and production efficiency.
The present invention is achieved like this, and the traditional handicraft that it has changed horizontal sandbox casting is vertical casting, and is incubated with the electrode carbon-point at the casting gate of mould, on one side casting, Yi Bian adopt mechanical drawing, the method for one side vibration.The temperature of its electrode insulation is 1400 ℃-1450 ℃, the blind capitiform for the treatment of product during drawing becomes the back with the drawbench drawing, the temperature of the drawing end during its drawing should remain on 900-1000 ℃, and the speed of drawing is per minute 90-100 centimetre, and drawing machinery vibration frequency is per minute 50-60 time.Entire method step of the present invention is to form through the batching of selecting materials, fusing, casting drawing, butt and processing silk mouth.
The invention has the advantages that the method that has adopted vertical casting, thereby kept mold core to be difficult for skew, and meanwhile the drawing of casting vibrate, so improved speed of production, overcome the formation of product sand holes, the product that product surface fineness is produced than traditional handicraft significantly improves.General performance is generally 70-80% in the finished product rate, has improved the finished product rate significantly.
Below with embodiment to the detailed description of the invention:
The present invention is finished by following steps:
1. the batching of selecting materials: major ingredient of the present invention selects 24 for use
#The pig iron is dosed material and is selected chromium, molybdenum and copper for use, and with the pig iron: chromium: molybdenum: copper=1000: 4: 4: 1 part by weight mixes;
2. fusing: the material that will prepare, whether the temperature with 1400 ℃-1450 ℃ in furnace cupola melts, and measure its component content simultaneously and meet the requirements;
3. casting drawing: adopt vertical casting, and be incubated with the electrode carbon-point at the casting gate of mould, casting on one side, adopt on one side mechanical drawing, on one side the method for vibration, the temperature of its electrode insulation is 1400 ℃-1450 ℃, the blind capitiform for the treatment of product during drawing becomes the back with the drawbench drawing, the temperature of the product drawing end during its drawing remains on 900 ℃-1000 ℃, and the speed of drawing is per minute 90-100 centimetre, and drawing machinery vibration frequency is per minute 50-60 time;
4. butt: after the product cold that drawing goes out, carry out butt according to different size;
5. process the silk mouth: will cut excessive product reprocessing silk mouth to become finished product.
