The thermal non-leakage probability is for large reactor cores about 0.95 – 0.98 and this value is minimally affected (in comparison with the other factors) by operational changes except changes in the moderator temperature.The only parameter, that influences the thermal non-leakage probability is the moderator temperature. It can be derived from the neutron diffusion theory, the probability

The New International Encyclopædia/Iron and Steel
Apr 27, 2017· In both cases the object is to burn away the silicon and carbon of the pig iron, and then to add carbon in the proper proportions to make steel. The reason for this seemingly inconsistent practice of first burning away the carbon and then adding the same material is as follows: Pig iron contains varying quantities of carbon, and to burn away
Converter (metallurgy) - Simple English Wikipedia, the
A converter is a chemical reactor which turns raw iron into steel.. Raw iron called pig iron which is the product of blast furnace, contains up to 4% of carbon.It is too hard and brittle for meaningful use. The carbon must first be burned off the iron to produce steel. This process is called conversion and the reactor a converter.. The first converter was invented by Sir Henry Bessemer in 1856.

It is similar in composition to crude pig iron as produced by the blast furnace. Its structure is crystalline and relatively brittle and weak in tension.
Use converter in a sentence | converter sentence examples
In the Bessemer or " pneumatic" process, which indeed might be called the " fuel-less " process, molten pig iron is converted into steel by having its carbon, silicon and manganese, and often its phosphorus and sulphur, oxidized and thus removed by air forced through it in so many fine streams and hence so rapidly that the heat generated by the oxidation of these impurities suffices in and by

Ironmaking 101 – From Ore to Iron with Blast Furnaces
Oct 10, 2017· Ironmaking Blast Furnace. Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace.. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities.

Lessons Learned During Medium-Frequency Coreless Induction
Jul 01, 2001· In sequence two, pig iron is added first. This is followed by the steel and then the sprue. The petroleum coke and SiC are added after 25% of the total charge is added to the furnace. In sequence three, the sprue is first, followed by the petroleum coke and SiC. The steel is added next and then the pig iron.
Energy Use in US Steel Manufacturing
From the data in Table 1 and Fig. 3 it is apparent that the production of hot metal or pig iron is the most energy intensive process for steel production at roughly 13.5 × 10 9 joules per ton (1000 Kg) of pig iron produced. The basic oxygen furnace is the second most energy intensive process at 11 × 10 9 joules per ton or steel produced. The Electric arc furnace has significantly less energy
Cast Irons: Composition and Properties | Alloys | Iron
(a) Carbon: As the carbon content increases, the melting point (as compared to steels) is lowered to between 1200° to 1140°C, and thus, carbon acts as a graphitiser. But, more the graphite formed, lower are the mechanical properties. (b) Silicon (0.5-3.0%): Silicon mainly controls the form of carbon present in the cast iron.
