Q:What do you mean by adding carbon to a table tennis racket?
The addition of carbon fibers increases the elasticity of the racket so as to increase the strength of the strike ball
Q:What is carbon accumulation?
Generally refers to the polycarbonate, PC, is a kind of thermoplastic plastics, good transparency, good mechanical properties, surface hardness, common uses such as CD, plastic glasses, a fence, protective window, public places, vacuum cleaners, coffee machine, juicer barrel, refrigerator shelf, pure such as the bucket.
Q:Use medium frequency furnace (1 million 500 thousand volt ampere) to produce 1 ton cast steel blank, how much kilowatt hour is consumed?
This depends on the intermediate frequency furnace voltage level and inverter efficiency, the general high voltage will save power, generally 550-700 range, details can refer to wcdlsb.net site medium frequency furnace data
Q:Does anyone know how much it costs to refine a ton of steel? What are the expenses involved?
now the steel profits are not as good as before, a ton of net profit is about 100 yuan
Q:What are the common defects in billet? What's the cause?
Five, X ray inspection, porosity, ultrasonic testing:One, 5, magnetic particle inspection, the back of the dent; 6, overheating and over burning: 1, penetrant inspection;Four. 2. The size of the weld does not meet the requirements and slag inclusion; 3 high-energy X-ray inspection, lamellar tearing and R ray flaw detection; 2;Five;Two: 1, arc crater;Methods for inspection of weld defects;
Q:What is the approximate cost of billet to cold rolling?
I think that the cost of steel billet plus manual consumption plus electricity and other costs divided by the finished product is greater than the cost per ton
Q:20 what is the difference between manganese silicon steel billet and Q235 billet?
20 manganese silicon steel billet for high strength steel,Q235 billet is almost the most common steel, requiring the lowest.
Q:Difference between billet, slab and billet
Production process of billet is through three methods: one is through the production of steelmaking and continuous casting equipment system, the molten steel is directly cast into the billet; two of steelmaking production systems of steel ingot or billet by rolling system of steel rolling equipment processing semi-finished products; three is the production of steelmaking system by forging semi-finished steel ingot the processing equipment. Market trends 1, domestic crude steel production remains high, although the domestic steel market has been relatively sluggish in recent times, and steel losses are more, but this does not seem to affect the enthusiasm of steel production. According to the China Steel Association statistics show that: in early April, the daily output of crude steel in key enterprises in China was 1 million 697 thousand and 300 tons, and the average daily output of crude steel in China was estimated at 2 million 123 thousand and 900 tons. And in mid April, crude steel daily output of ten days, although there has been a drop back, but still at a high level. According to statistics, in mid April, the average daily output of crude steel in key enterprises nationwide was 1 million 689 thousand and 100 tons, and the average daily output of crude steel in China was estimated at 2 million 115 thousand and 800 tons. Such a large production and sluggish demand in stark contrast, which is a drag on steel prices down one of the important factors.
Q:Is the reaction of carbon and carbon dioxide a redox reaction?
Is the redox reflect the oxidizing agent is CO2 C 2009-10-22, the reducing agent is the oxidizing agent is CO2, is C 2009-10-22 reductant is redox reaction. Price reduction in carbon dioxide carbonation, was reduced, so is the oxidant.
Q:If the casting speed is not steady, what will happen to the billet?
Secondly, the speed of cutting is unstable, and the cut rate will be reduced.
