Defeitos de qualidade de bobinas de aquecimento elétrico e sua prevenção

(1) High yield. The method used to produce round tube blanks eliminates the residual steel loss of the middle injection tube and the soup path when the tube blanks are produced by die casting, and improves the yield of molten steel. At the same time, because the ingot does not need a heat preservation cap, it is not necessary to remove For the head of the steel ingot, its yield can be increased by 10%-15%.
(2) Alterações nas condições de produção . A produção de espaços em branco do tubo redondo tem um grau muito mais alto de mecanização e automação do que a produção de fundição, o que altera bastante a intensidade do trabalho .
(3) The process is simplified. The method is adopted to produce round tube blanks, and the intermediate processes such as demolding and whole ingot in the die casting process are omitted. Especially when steel ingots cannot be directly used for pipe rolling, it is necessary to heat and rough-roll (forge) the die-cast steel ingots, which increases the production process. Obviously, the Processo de produção do tubo redondo em branco é mais simples e o custo de produção é menor .
(4) Save energy. In the production of round billets, once the hot delivery and hot charging process is realized, part of the fuel required for heating of the billets can be omitted, thus greatly reducing energy consumption. It can be seen that the round tube billet directly used in the production of heating coils has brought a profound revolution to the heating coil manufacturing industry due to its low cost and good Qualidade .
