Description
Patented F eb. 20, 1934 William ,H. Seaman, Hammond, Ind.
No Drawing. Application October 2, 1930 Serial No. 486,042
0 Claims. (01. 80-58) The present invention relates in general to a novel alloy of iron for use in a chilled cast iron roll employed for rolling metal articles and in particular to a chilled iron alloy roll having a chill" or a definite chill as it is sometimes called.
One of the objects of the presentinvention is to provide an alloy iron of such character that the hardness of the working depth or chill may be increased. I
Another object is to provide a novel alloy of iron in which the toughness of the working depth or chill may be increased.
Another object is to provide an iron alloy which when'cast in chilled roll will increase the amount of work that may be done with it before it is dressed. I
A further object is to provide a novel iron alloy which is easier handled in casting in a chilled mold and which will give more uniform characteristics.
Still another object is to provide a novel iron alloy which is particularly beneficial in obtaining an iron alloy roll that may be substituted for a forged steel roll and which will give better results in such cases.
There are other objects of my invention which, together with the foregoing, will be described in the detailed specification which is to follow:
I have ascertained that the addition of molybdenum to a large number of alloys, having, as
modifying constituents, carbon, manganese, silicon, sulphur, phosphorus, chromium and nickel,
has a very advantageous effect in that with the modifying ingredients properly proportioned for any particularly desiredwork it will greatly increase its hardness and toughness and that the alloy, when cast in a chilled mold, will provide a roll that wears better and has longer life.
The quantity of the product that may be turned out by such aroll is greatly increased before the 0 roll has to again be dressed, and the alloy itself is easier to handle in casting. Further, an alloy of more uniform character is obtained in this manner. The proportion of molybdenum with the various other modifying elements mentioned is given below and may be proportioned to give alloys of varying characteristics in a manner well understood by those skilled'in the art To Mn s1 s P Cr Ni 1 M5 1 2.60 .10 .20 .05 .05 .15 1.25 .15 to to to to to to to to 3.35 .40 1.00 .20 .55 1 .05 a 5.00 l .50
forms its well known function of tending to control the hardness, the nickel also having a hardening efiect.
It is to be pointed out that the alloys generally are somewhat similar in character to those disclosed in my (ac-pending application, Serial No. 449,686, filed May 3, 1930, with the addition of molybdenum. In fact, alloys having the same and ingredients to secure thesame.
'r.o. Mn 81 s P Cr Ni 70to80 to to to to to to to 3.15 .15 .25 .115 .15 .25 3.00 80to90 to to to to to to to 00 to 100 3.25 to to to m m to My invention may be variously modified without departing from the spirit and scope thereof, as set forth in the appended claims.
I claim:
1. A cast iron alloy chilled roll, the alloy including as modifying elements carbon from 2.60% to 3.35%, manganese .10% to .40%, chromium .15% to .65%,. nickel 1.25% to 5.00%, and molybdenum in substantially'the same proportion as the chromium.
2. A cast iron alloy chilled roll, the alloy including as modifying elements carbon from 2.60% to 3.35%, manganese .10% to .40%, silicon .20% to 1.00%, chromium .15% to .65%, nickel 1.25% to 5.00%, and molybdenum .15% to 50%.
3. A cast iron alloy chilled roll, the alloy including as modifying elements carbon from 2.60% -to 3.35%., manganese .10% to 40%, silicon 20% to 1.00% to 1.00%, sulphur .05% to 200%, chromium 15% to .65%, nickel 1.25% to 5.00%, and molybdenum .15% to 4. A cast iron alloy chilled roll, the alloy including as modifying elements carbon from 2.60% to 3.35%, manganese .10% to .410 silicon 20% to 1.00%, sulphur .05% to 200%, phosphorus .05% to chromium 15% to .65%, nickel 1.25% to 5,00%, and molybdenum .15% to 50%.
5. A cast iron alloy chilled roll, the alloy including as modifying elements total carbon 2.60%
'and having molybdenum for increasing the toughness and hardness of the wearing surface in the proportion of .15% to .50%.
7. A chilled. iron alloy roll'having a definite chill and containing a hardening and toughening agent such as carbon and nickel, in an amount within certain limits to produce a desired degree of hardness and toughness, and also containing a chill affecting ingredient such as" silicon in amount between certain limits to cooperate with the amount of hardening and toughening agent employed and not to exceed 1.0, and also ,containing a further hardening agent.
8. A chilled iron alloy roll containing a hardening and toughening agent such as carbon and nickel, in amount between certainlimits to secure ening and toughening agent such as carbon and nickel, in amount between certain limits to give a desired degree of hardness and toughness, and also containing silicon, manganese, chromiiim and sulphur in amounts between certain limits, so that the silicon and manganese will act to control the chill and the chromium and sulphur to givethe desired qualities in view-of the amount of hardening and toughening agent employed the silicon being not to exceed 1.0 and the man ganese not to exceed .40 and the chromium not to exceed .65, and also containing molybdenum to act as a hardening agent in cooperation with the other ingredients.
