摘要： PURPOSE:To feed powder efficiently by providing a screw feeder at the lower end outlet of powder hopper while providing an air slide at the inlet and couplling the outlet through a uniform pressure tube to the upper portion of hopper thereby fluidizing the power with air. CONSTITUTION:In order to feed power from a hopper 1 to a transportation line 10, a screw feeder 3 and a ribbon screw 22 are driven by a motor 20 while air is fed from the lines 12, 30 to an ejector 9 and an air slider 25. Consequently, powder is carried from the outlet 2 through the screw feeder 3 to the ejectror 9 then transported on gas to the line 10. Here, the air ejected from the air slider 25 upward will fluidize power near the outlet 2 and in the hopper 1. Upon reaching to the upper end of hopper 8, the air will flow through an uniform pressure tube 35 to the discharge port 7 of screw feeder resulting in prevention of choking of the discharge port 7.

摘要： PURPOSE: To obtain magnesian powder for melt-spraying easy to sinter and melt in a flame by calcining magnesite at a specified temp.
CONSTITUTION: Magnesite is calcined at 700W1,650°C. When the calcining temp. is below 700°C, thermal decomposition represented by MgCO
3 →MgO+CO
2 is caused during melt-spraying to drop the temp. of a flame, or the decomposed gas is tightly sealed in a melt-sprayed layer to induce a foaming phenomenon, thereby resulting in a lower melt-spraying yield and deteriorated density, strengh and corrosion resistance of the sprayed layer. When magnesite is calcined at >1,650°C, periclase crystals are grown to 20W100μm to reduce the specific surface area and the open pores, so the propagation of heat is made difficult to prevent the instantaneous melting of the powder in a flame, thereby resulting in a lower spraying yield and deteriorated density and corrosion resistance of the sprayed layer. In addition, the cost of fuel is increased because of high temp. calcination. Magnesia thus obtd. is pulverized to about 30W100μmwt. average diameter in consideration of feedability during spraying.

摘要翻译：目的：通过在特定温度下煅烧菱镁矿，获得易于熔融熔化的镁粉，并在火焰中熔化。构成：在700-1,650℃煅烧菱镁矿。当煅烧温度在700℃以下，在熔融喷涂过程中引起由MgCO3 MgO + CO2表示的热分解，以降低温度。或者将分解气体紧密地密封在熔喷层中以引起发泡现象，从而导致喷射层的较低的熔喷速率和劣化的密度，强度和耐腐蚀性。当菱镁矿在> 1650摄氏度煅烧时，晶体硅酸盐晶体生长至20-100μm，以减小比表面积和开孔，因此难以传播热量以防止粉末在火焰中瞬间熔化，从而导致喷涂成品率降低，喷涂层的密度降低和耐腐蚀性降低。另外，由于高温，燃料成本增加。煅烧。氧化镁因此得到证实。粉碎至约30-100重量％。考虑到喷雾期间的可进给性的平均直径。

摘要： PURPOSE:To obtain having a great number of open pores and capable of instantaneously melting in a high-speed flame and also of forming a high quality flame- coated layer by baking and crushing a metal compound convertible into oxide by thermal decomposition at a temperature above its thermal decomposition temperature but below a specific temperature at which its activity is not lost. CONSTITUTION:Aluminum hydroxide is mixed under wet condition, molded, baked, and then crushed into fine powder. The powder thus obtained is quantitatively supplied into propane-oxygen flame for flame coating. In this way, with the powder baked at a temperature at which its activity is not lost, a molding which has a large number of open pores, a high activity, a high heat flow propagativity, and instantaneous meltability in flame, as well as high denseness, high strength, high corrosion resistance, and high spalling resistance can be obtained.

摘要： PURPOSE: To improve adhesivity of a lining layer by flame spraying and to bond the layer to a wall of a coke oven, by removing attached carbon, etc. from the wall surface of the coke oven through exidizing flame of a flame gun, followed by flame spraying of refractory powder.
CONSTITUTION: After coke is taken out from a coke oven by a coke pushing machime, carbon and tar deposited on a repairable part of a wall of the coke oven is removed by oxidizing combustion of a flame gun. The wall is coated with fefractory powder by flame spraying to form a lining layer, which has improved adsecitity. When the refractory powder is applied by flame spraying to the wall of the coke oven while it and hot bed are maintained at a temperature of not less than 400°C by oxidizing flame in removing carbon, the linining layer has improved adhesivity.
