Export From Taiwan

August 7, 2016, it is another exciting moment for Hanhai Metallurgy, the customized 10 cubic meters metallurgical slag tank for Treasure Island Taiwan is about to be shipped, take its glorious mission and go!   Competitive metallurgical slag tank market, how to sell the product is every slag tank manufacturers are concerned about the topic. In the era of wine is also afraid of deep alley, and then good metallurgical slag tank products can not be separated from the promotion and marketing. As a metallurgical slag can manufacturer in Henan, Hanhai Metallurgy believes that slag can manufacturers want to improve sales, expand sales, it is important to build the slag can product power. Build product power is the basic bottom line of the enterprise. Generally speaking, each slag tank manufacturer has its own positioning, therefore, some slag tank manufacturers do not do their best in processing cast steel parts. As a well-known domestic metallurgical slag tank manufacturers, Hanhai Metallurgy believes that no matter how the company's positioning, in processing slag tank cast steel products should be as high quality as possible, in line with national and industry-related standards, to meet the needs of users. Slag tank cast steel parts to form a “product power”, or need to work on the casting process.

How is the quality of the large gear ring of the steel casting processing plant ensured?

Large gear ring cast steel parts in the design will have to follow the principles set out, and at the same time need to be reserved size as well as material and so on into account. At the same time processing large gear process can also enhance its bearing force as well as precision, so that large gear cast steel parts not only have a relatively high wear resistance, but also be able to withstand a certain impact load capacity, and at the same time to choose a good material, so that it has a high degree of toughness.   For example, the large gear is one of the important accessories in the dryer, cast steel parts processing manufacturers will be processed according to the different requirements for the use of the dryer, so the user in the choice of the time, can not be generalized, choose the right for their own is * important. Cast steel parts manufacturers in the processing of products will have what technical requirements? 1, casting out of the large gears used are alkaline electric furnace or electric furnace steel. 2, there can not affect the strength of the casting defects, especially defects after welding to eliminate internal stress, while the part of the hardness can not be less than ten percent of the hardness of the parent body. 3, ball mill large gear ring of the tooth surface and the cam can not exist to make up the casting, but can be less than 5 millimeters, the depth is less than 3 millimeters or so of defects. 4, large gear cast steel parts in the processing must be heat treatment before, mainly in order to be able to eliminate internal stress, improve its hardness. 5, processing should pay attention to the large gear ring cast steel parts of the bonding surface, so as to facilitate the subsequent two half gears can be assembled together. 6, the processing of large gears, you need to be in the gear on the side of the engraved indexing circle line. In addition to the above simple introduction of several requirements, there are other requirements that require special attention, cast steel parts processing manufacturer next issue for you to explain. Later in the process of installation, remember to clean up the surrounding obstacles first, make a good mark, adjust the size of the gear clearance and side clearance, etc., will be conducive to the subsequent operation.
