Hongxing Focus on Technology Level of Rotary Kiln
The most important things chinese cement rotary kiln production enterprises faced are the industrial structure adjustment,which must adapt to the most stringent environmental standards, the new cement rotary kiln has completely turned to the development of environmentally friendly direction, the introduction of a new dry-process cement rotary kiln production process-driven stage. Henan Hui cement grinding station layout cement clinker production bases in six provinces and one city, during the Eleventh Five to enter the mine equipment manufacturing industry, our company totally invest 48 cement rotary kiln production line, cement rotary kiln sophisticated and standardized. The average size of the rotary kiln production line is the first to achieve industrial upgrading will not solve the problem. Its cement rotary kiln design Institute inventive, new clinker production capacity pioneers entering Zhejiang carried out large-scale, large-scale acquisition. And promote the regional industrial structure adjustment.
Our company mainly produce rotary kiln for ore dressing,30 years of industry experience to create top quality, Our rotary kiln equipment is trusted by many customers at home and abroad.What should spare Rotary Kiln welding work before?
1.The rotary kiln shell welding work must be qualified in the rotary kiln shell is looking after, and the use of welding gear rotary kiln.
2.Electrode selection: rotary kiln electrode welds to ensure its quality should not be less than the mechanical properties of the base metal mechanical properties, welding process parameters and the specific implementation requirements of the drawings. Drawing no requirements, must develop welding instructions. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery, like ore concentrate, Henan Hongxing is always doing the best in products and service.china vibrating feeder:http://www.hx-china.com/11.html
3.To participate in the rotary kiln shell welding welder, must pass the examination are allowed to officially participate in the rotary kiln shell welding. Normally two test panels of each welder welding, bending and tensile strength required to intercept test specimens for bending and tensile strength tests. Test panels of material, groove forms, welding processes are the same requirements and formal welding.
4.Used for rotary kiln shell welding electrodes, must be dried before use, in the dry box, the temperature of 250 ~ 300 ℃, drying time is 1 ~ 2h. Dried down to about 150 ℃ temperature preservation, on the insulation tube, used with the check, to avoid staying too long in the air.
5.Before the deal rotary kiln cylinder welding groove in the form, size check, not a groove at the delamination crack, slag and other defects affecting the quality, welded joints before welding on both sides should be 30 ~ 50mm wide paint , rust and other dirt cleaned, exposing metallic luster to start welding.
The rotary kiln is generally operated under the negative pressure. The connection means between the rotating cylinder and the fixed parts, such as the kiln hood, kiln hood and the kiln body. There are some gaps. In order to prevent the outside air being sucked into the kiln and to prevent the leaking of the materials in the kiln, the sealing device is very necessary, which can be used to adapt to the form error.
