  生物质颗粒机主要易损件—环模;其质量的好坏直接影响颗粒消费者的消费本钱和熄灭颗粒质量。据不完整统计,环模损消耗占整个消费车间的维修费的30%以上,熄灭颗粒质量的好坏更是对颗粒的销售产生极大的影响。可见,如何对环模停止正确选用、合理运用和有效的维护对颗粒消费者来说是极关重要的。
  The main vulnerable part of biomass granulator is ring mould, whose quality directly affects the consumption cost of granular consumers and the quality of extinguished granules. According to incomplete statistics, the consumption of ring dies accounts for more than 30% of the maintenance cost of the whole consumer workshop, and the quality of extinguished particles has a great impact on the sales of particles. It can be seen that how to stop the correct selection, rational use and effective maintenance of the ring die is very important for the particle consumers.
  环模是一种多孔性环形易损件,壁薄,模孔密布,装配尺寸精度高。工作时,颗粒在旋转的环模及压辊的挤压下,从内壁经过模孔向外成条状挤出,再由切刀切成所需长度的颗粒。下面对环模选用、运用及维护作些浅析,以供大家参考。
  Ring die is a kind of porous ring vulnerable parts with thin wall, dense die holes and high assembly accuracy. When working, the particles are extruded in strips from the inner wall through the die hole under the extrusion of the rotating ring die and the roller, and then cut into the required length particles by the cutter. The following is a brief analysis of the selection, application and maintenance of the ring die for your reference.

  环模的选用;环模普通由碳钢或合金构造钢,或者不锈钢经锻造,机加工、钻模孔及热处置等工序制做而成。目前,国内市场盛行的环模有高有低,其主要缘由是在选材、工序选用和控制等方面的不同形成的。国内一些小厂消费的环模主要由碳钢或合金构造钢经锻造,麻花钻钻削模孔,再经普通热处置加工而成。这样的环模在消费过程中通常呈现这样或那样的问题,如新模装机需经长时间的洗模工序,能耗高,产量低,颗粒质量差及爆模等现象。另外还有一个更为严重的问题就是运用寿命低,不耐磨,据一项调查显现,应用这些环模消费的颗粒中铁含量较高,从而极大影响了熄灭颗粒的质量,这一结果主要是由环模的耐磨性差所形成的。市场经济的不时开展,
  The selection of ring die; ring die is usually made of carbon steel or alloy structural steel, or stainless steel by forging, machining, drilling die hole and heat treatment processes. At present, there are high and low ring dies prevailing in the domestic market. The main reason is the difference in material selection, process selection and control. The ring dies consumed by some small factories in China are mainly forged from carbon steel or alloy structural steel, drilled by twist drill, and then processed by ordinary thermal treatment. This kind of ring die usually presents such or other problems in the process of consumption, such as the installation of new die needs a long time of mould washing process, high energy consumption, low output, poor particle quality and explosion die and other phenomena. Another more serious problem is the low service life and non-wear resistance. According to a survey, the iron content in the particles consumed by these ring dies is higher, which greatly affects the quality of the extinguished particles. This result is mainly caused by the poor wear resistance of the ring dies. Market economy develops from time to time.

  中国世贸组织的参加,只要价廉物美的颗粒才具有市场竞争力。关于颗粒消费者来说,降低消费本钱和进步熄灭颗粒质量是迫切需求的,而这些质量的上下很大水平上由环模的质量停止基本保证。依据环模的工作情况,颗粒消费者应选用那些选材合理、设备先进及工艺合理的消费厂消费的环模。应选用不锈钢制环模,环模选用不锈钢锻坯,是环模运用寿命高的实质保证;应选用经枪钻加工的模孔,应用多工位枪钻对模孔停止加工,能保证模孔润滑,不会构成歪孔(即模孔中心线与环模圆周中心线不同轴),从而到达环模出料快,颗粒质量好(颗粒外表润滑,颗粒平均,颗粒粉化率小等)等特性;应选用经真空热处置的环模,对环模停止真空热处置是对前几工序加工质量的进一步保证,它保证了环模资料的高耐磨性、高强度,以及对模孔的润滑度停止了有效的维护(防止了模孔的氧化)。
  China's participation in the WTO requires only cheap and good quality particles to be competitive in the market. For granular consumers, it is urgent to reduce the cost of consumption and improve the quality of extinguished granules, which is largely guaranteed by the quality of the ring die. According to the working condition of the ring die, the consumers of particles should choose the ring die which is consumed by the consumer factories with reasonable material selection, advanced equipment and reasonable technology. Stainless steel ring die should be selected, and stainless steel forging blank should be used in ring die, which is the essential guarantee for high service life of ring die; the die hole processed by gun drill should be selected, and multi-station gun drill should be used to stop the processing of die hole, which can ensure the lubrication of die hole, and will not form a deviated hole (i.e., the center line of die hole is different from the circumferential center line of ring die). The annular die has the characteristics of fast discharging, good particle quality (particle surface lubrication, average particle size, small particle pulverization rate, etc.). The annular die after vacuum heat treatment should be selected to stop the vacuum heat treatment of the annular die is a further guarantee for the processing quality of the previous processes, which ensures the high wear resistance, high strength of the annular die data and the die hole. The lubricity of the die stops effective maintenance (prevents the oxidation of the die hole).
  综上所述,合理选用优质的环模是颗粒消费者降低消费本钱、进步颗粒质量的关键。想要了解更多内容,欢迎访问生物质颗粒机生产厂家网站:http://www.longtengkeliji.com
