熱覆膜砂 的英文怎麼說
中文拼音 [rèfùmóshā]
熱覆膜砂
英文
hotprecoatedsand-
It can measure shell speed and crusting of film laminating by adopting fks - 1 tester of film laminating capacity ; the principle of this instrument is that it makes film laminate on heating plate and turns 90or 180 of heating plate for moving un - shell sand. and then it measures shell thickness and observes cocking condition of surface sand
採用fks - 1型覆膜砂結殼性能測試儀可以觀測覆膜砂的結殼速度和起皮狀況,其原理是將覆膜砂撒在加熱板上,經過某一時間之後,將加熱板旋轉90或180移去未結殼的鬆散砂,然後測量結殼厚度,並觀察表層砂的翹起情況。Xs2125 type film laminating sand heating product line
Xs2125型覆膜砂熱法生產線In addition, there will be some asymmetrical condition for shelling ; if the shell speed is different, there will be crusting phenomenon and then damage precision of shell thickness
另外一些覆膜砂還可能出現結殼厚度不均勻的現象,如果結殼速度不同,將出現覆膜砂加熱過程中的「起皮」現象從而破壞了結殼厚度的準確性。The results denote that the sand layer can greatly enhance heat transfer in high temperature region because it changes film boiling to liquid film evaporation in the sand layer
在高溫金屬面上覆蓋砂層后,可將高溫面上的膜沸騰轉化為砂粒表面的液膜蒸發,從而大幅度提高表面換熱系數,強化冷卻能力。This equipment fits for heating new sand with precoated sand heating method, main fuel is coal or broken hard coke
本設備主要用於覆膜砂熱法生產對新砂的加熱,主要燃料為煤或碎焦碳。This equipment fits for heating new sand with cladding sand heating method, its main fuel is coal or dispersed coke
