100 results about "Critical control point" patented technology

Critical Control Point (CCP) is the point where the failure of Standard Operation Procedure (SOP) could cause harm to customers and to the business, or even loss of the business itself. It is a point, step or procedure at which controls can be applied and a food safety hazard can be prevented, eliminated or reduced to acceptable (critical) levels. The most common CCP is cooking, where food safety managers designate critical limits. CCP identification is also an important step in risk and reliability analysis for water treatment processes.

Smelting method of 9Ni steel

ActiveCN102747181AMeet the requirements of continuous castingReduce lossesManufacturing convertersCritical control pointSmelting process
A smelting method of 9Ni steel. The method has the following characteristics: 1.a smelting process comprises steps of pretreatment on molten iron (desulfuration), converter (double dephosphorization, melting nickel plate), LF furnace (desulfuration) and RH (degassing); 2. dephosphorization is conducted in the converter and comprises two steps: step one: blending molten iron desulphurized by KR and steel scrap into a dephosphorization converter for primary smelting, using ''dephosphorization converter smelting critical control point'' to desulphurize the molten iron to a phosphorus content below 0.020%, and carrying out semi-steel tapping; and step two: blending the molten semi-steel and nickel plate into a decarburization converter for converting, desulphurizing the molten steel after converting to a phosphorus content below 0.003%, and carrying out tapping; and 3. the nickel plate is melted in the decarburization furnace. According to the present invention, the two-step dephosphorization is carried out in the converter that molten steel after converting has low phosphorus content and is stably controlled, so as to benefit improvement on the yield of 9Ni steel. Decarburization converter slag has low phosphorus content, and ladle molten steel has a low rephosphorization amount, so as to clear out molten steel in the decarburization furnace and reduce molten steel loss in a steel leaving operation.
