混凝土自動攪拌車配件襯板對生產混凝土的影響

由于水泥混凝土在交通、水利、建筑等職業中需求量很大,因而各種類型的混凝自動土攪拌車,尤其是大型自動化連續式攪拌設備得到很多運用。攪拌葉片和攪拌機襯板是攪拌設備中的易磨損件,前進它們的抗磨損功能,延伸更換周期,可前進攪拌功率,具有明顯的經濟效益。水泥混凝土由水泥、水、砂、石料和外加劑等攪拌而成。攪拌機Ⅱ十片、襯板等相對球磨機襯板而言所受沖擊力要小很多,但襯板壁更?。ǎ保埃瑁椋頂[布),為保證搬運及裝置進程不致開裂.故請求有滿意的耐性。
Due to the great demand for cement concrete in transportation, water conservancy, construction and other occupations, various types of automatic concrete mixer, especially large-scale automatic continuous mixing equipment, have been widely used. Mixing blade and mixer lining plate are easily worn parts in mixing equipment. Advancing their anti-wear function, extending the replacement cycle, advancing mixing power and obvious economic benefits. Cement concrete is composed of cement, water, sand, stone and admixtures. Compared with the lining plate of ball mill, the impact force on the ten pieces and lining plate of mixer II is much smaller, but the lining plate wall is thinner (at the mercy of 10him). In order to ensure that the handling and device process will not crack, it is required to have satisfactory patience.
其損壞方法為濕式磨損。如今很多運用的抗磨材料l5Cr系列高鉻鑄鐵質料,組織中抗磨骨架相M7c3型碳化物與基體電位差大。濕式磨損工況下,襯板的基體組織會遭到電化學腐蝕。由于周圍被腐蝕的基體不能很好地支撐維護碳化物,使碳化物在磨損時遭到剪切力效果而折斷或掉落,無法表現出的抗磨損功能。
The damage method is wet wear. The potential difference between M7C3 carbide and matrix of wear-resistant skeleton phase in l5cr series high chromium cast iron is large. Under the wet wear condition, the matrix structure of the liner will suffer electrochemical corrosion. Because the surrounding corroded matrix can not well support and maintain the carbide, the carbide is broken or dropped due to the effect of shear force during wear, which can not show the anti-wear function.
從前試用28CrMo2Cu ̄質襯板,運用效果非常好??墒怯捎阢f是寶貴金屬,使其運用遭到限制。相比之下,中國錳資源豐富,錳鐵價格低廉筆者有在15Cr高鉻鑄鐵中以錳代鉬的成功運用經歷J這篇文章經過28cr鑄鐵以錳代鉬實驗,并與別的幾種常用耐磨材料進行抗腐蝕性、抗磨性對比,企圖挑選一種既經濟又具有抗腐蝕磨損功能的攪拌機襯板質料。
In the past, 28crmo2cu  ̄ quality lining board was tried, and the application effect was very good. However, because molybdenum is a precious metal, its application is limited. In contrast, China is rich in manganese resources and the price of ferromanganese is low. The author has the successful application experience of substituting manganese for molybdenum in 15Cr high chromium cast iron. J this paper attempts to select a kind of mixer lining material with both economic and anti-corrosion wear function through the experiment of substituting manganese for molybdenum in 28Cr cast iron and the comparison of corrosion and wear resistance with several other common wear-resistant materials.
