| 20110256420 | HOT-DIP GALVANIZED STEEL PLATE AND PRODUCTION METHOD THEREOF - The invention provides a hot-dip galvanized steel plate with high adhesion between a plating layer and base steel, and belongs to the field of manufacturing hot-dip galvanized steel plates. Atomic concentration ratio Al/Zn of Al and Zn in a Fe-Al intermediate transition layer between a base steel and a plating layer of the hot-dip galvanized steel plate is 0.9-1.2. The plating layer did not have Γ phase, but has relatively thin δ phase and little ξ phase. The plating layer mostly consists of η phase, thus obviously improving adhesion, scratch resistance and wear resistance of the plating layer. | 10-20-2011 |
| 20110253268 | HIGH CARBON CONTENT AND HIGH STRENGTH HEAT-TREATED STEEL RAIL AND METHOD FOR PRODUCING THE SAME - A high carbon content and high strength heat-treated steel rail including by weight 0.80-1.20% carbon, 0.20-1.20% silicon, 0.20-1.60% manganese, 0.15-1.20% chromium, 0.01-0.20% vanadium, 0.002-0.050% titanium, less than or equal to 0.030% phosphorus, less than or equal to 0.030% sulfur, less than or equal to 0.010% aluminum, less than or equal to 0.0100% nitrogen, and iron. The steel rail has excellent wear resistance and plasticity and can satisfy the requirement for overloading. A method for producing the steal rail by heating a slab to a heating temperature, multi-pass rolling, and accelerated cooling, wherein a maximum heating temperature (° C.) of said slab is equal to 1,400 minus 100[% C], [% C] representing the carbon content (wt. %) of said slab multiplied by 100. | 10-20-2011 |
| 20110182787 | METHOD FOR PRODUCING TITANIUM TETRACHLORIDE BY USING LOW-GRADE TITANIUM MATERIAL - The invention provides a method for producing titanium tetrachloride by using a low grade titanium material, and belongs to the chemical field. The technical problem to be solved is to provide a method for producing titanium tetrachloride by using a low grade titanium material capable of continuous industrialized production. The method is characterized in that the low grade titanium material containing a certain proportion of titanium carbide is caused to directly react with chlorine at 600-700° to produce the titanium tetrachloride. Long-time continuous and stable operation can be realized by using the process parameters of the method, and chlorination rate of the titanium carbide in the titanium material reaches above 90%, so that the titanium material can be better used for producing the titanium tetrachloride. | 07-28-2011 |
| 20100243468 | METHOD FOR PREPARING METALLIC TITANIUM BY ELECTROLYZING MOLTEN SALT WITH TITANIUM CIRCULATION - The present invention provides a method for preparing metallic titanium by electrolyzing molten salt with titanium circulation. The method mainly comprises reducing titanium tetrachloride (TiCl | 09-30-2010 |
